What is AA similarity rule?
If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable.
Similar figures are items that feature more than two figures that are the same form but different sizes.
Despite having the same form, each might have different sizes.There are no matching angles that are not equal.Similar equivalent side ratios exist.When two triangles are comparable, all of their matching angle pairs and sides are congruent and proportionate. However, you do not necessarily need to have information about all of the sides and angles of two triangles in order to be certain that they are identical.
AA similarity rule
So, ∠ adc is 52.8°
and ∠ dac is 26.7°
So, the ratio of dac/adc = 0.506
And the ratio of side will also be equal as well which is 1.8

A single card is drawn from a standard 52 card deck fund the conditional probability that the card is a spade given that it is a 10
When the card is a jack, there is a 0.25 probability that you will receive a spade.
What is probability?The ratio of good outcomes to all possible outcomes of an event is known as the probability.
The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an event can be calculated using the following formula.
Probability(Event) = Positive Results/Total Results = x/n
In order to better grasp probability, let's look at a straightforward application. Let's say we need to forecast if it will rain or not. Either "Yes" or "No" is the appropriate response to this query.
There is a chance that it will rain or not. Here, probability can be used. Using probability, one may forecast the results of a coin toss, a roll of the dice, or a card draw.
According to our question-
P(Spade) = 13/52 = 1/4 P(Jack) = 4/52
= 1/13 P(Spade and Jack)
= (1/4)(1/13) = 1/52 P(Spade/Jack)
= P(Spade and Jack)/P(Jack)
= (1/52)/(1/13) = (1/52)(13/1)
= 13/52 = 1/4 = 0.25
Hence, When the card is a jack, there is a 0.25 probability that you will receive a spade.

Mackenzie is trying to find the height of a radio antenna on the roof of a local
building. She stands at a horizontal distance of 29 meters from the building. The
angle of elevation from her eyes to the roof (point A) is 24°, and the angle of
elevation from her eyes to the top of the antenna (point B) is 32°. If her eyes are 1.71
meters from the ground, find the height of the antenna (the distance from point A to
point B). Round your answer to the nearest meter if necessary.
The antenna's height is determined to be 10 m using right triangle relations.
What are the relations in a right triangle?Following are the relationships in a right triangle:
The sine of an angle is equal to the length of the hypotenuse divided by the length of the side opposite the angle.
The cosine of an angle is equal to the neighboring side's length divided by the hypotenuse's length.
The tangent of an angle is calculated by dividing the length of the angle's adjacent side by its opposite side.
So, n this case, the side opposite to the 17o angle is the vertical height from her eyes to the top of the antenna, and the next side is the horizontal distance of 29 m, then:
tan 17° = h/29
h = 29 tan 17°
h = 8.87
Including eye height:
h = 8.87 + 1.51 = 10.38 m.
The antenna is 10 meters tall, rounded to the nearest meter.
Therefore, the antenna's height is determined to be 10 m using right triangle relations.

trying to find the arc length of the arc for the polar curve r=8cosθ between 0 and π4
Answer:
Step-by-step explanation:
To find the arc length of the polar curve r = 8cosθ between 0 and π/4, we can use the formula for arc length:
L = ∫a^b √(r^2 + (dr/dθ)^2) dθ
Substituting in the values for r and dθ, we get:
L = ∫0^(π/4) √(8^2cos^2θ + (-8sinθ)^2) dθ
= ∫0^(π/4) √(64cos^2θ + 64sin^2θ) dθ
= ∫0^(π/4) √(64) dθ
= ∫0^(π/4) 8 dθ
= 8(π/4 - 0)
= 8π/4
= 2π
Therefore, the arc length of the polar curve r = 8cosθ between 0 and π/4 is 2π.

If y varies inversely as x2 and y=38 when x=18, find y if x=20.
The required value of y for the given inverse relation is 30.78
What is the inverse variation?
Inverse variation occurs when one variable varies inversely with respect to another. It represents the inverse relationship between two quantities are two quantities.
In mathematics, inverse variation refers to the relationships between variables that are expressed as y = k/x, where x and y are two variables and k is a constant value. It states that if the value of one quantity rises, the value of the other quantity falls.
Given, y varies inversely as [tex]x^{2}[/tex]
That is, y∝ 1/ [tex]x^{2}[/tex]
or, y = k/ [tex]x^{2}[/tex]
or, [tex]x^{2}[/tex]y = k
And, y=38 when x=18
Then, [tex]18^{2}[/tex]*38 = k
k = 12312
Now, if x=20 then y=?
[tex]x^{2}[/tex]y = 12312
or, [tex]20^{2}[/tex]*y = 12312
or, 400y = 12312
or, y = 12312/400 = 30.78
Hence, the required value of y is 30.78

Answer:
x² +8x -15 = 0
Step-by-step explanation:
You want a quadratic such that the sum of the roots is -8 and their product is -15.
CoefficientsWhen the roots of a quadratic are p and q, its factored form is ...
(x -p)(x -q) = 0
The expanded form of this is ...
x² -(p+q)x +pq = 0
That is, the coefficient of x is the opposite of the sum of the roots, and the constant is the product of the roots.
ApplicationHere, we want the sum of roots to be -8, so the x-coefficient will be the opposite of that: 8. The constant will be the product of the roots: -15. That makes the desired quadratic be ...

After solving, the maximum height of the ball is 90.25 feet.
In the given question,
A person standing close to the edge on top of a 48-foot building throws a ball vertically upward.
The quadratic function
h(t) = -16t^2+52t + 48 models the ball's height about the ground, h(t) in feet, t seconds after it was thrown.
We have to find the maximum height of the ball.
Height is given that;
h(t) = -16t^2+52t + 48
Now comparing the given equation by the standard equation ax^2+bx+c=0
Here b = 52, a = -16
For maximum height put t= -b/2a
t = -52/2(-16)
t = 52/32
t = 1.625
Maximum height
h(1.625) = -16(1.625)^2+52(1.625) + 48
h(1.625) = -42.25+ 84.5 + 48

If an object is dropped from a height of 85 feet, the function h(t) = -16t2 +85 gives the height
of the object after t seconds. Approximately, when will the object hit the ground?
Answer:
Step-by-step explanation: h(t)=-16t2+85
Let h(t)=0 to find when the object will hit the ground
0=-16t2+85
Solve for t=?
We need to get t term on its own
Take 85 from both sides
0-85=-16t2+85-85
-85=-16t2
To get t term on its own
Divide both sides by -16
-85/-16=-16t2/-16
5.3=t2
We have to solve for t squared that means we must take the square root of both sides
the square root of 5.3=gives + or - 2.3 seconds we can't have negative time so discard -2.3 seconds
