Answer:
sin A = 13/85
Step-by-step explanation:
Opposite Angle A is side BC, of length 13. The length of the hypotenuse is 85. The sine function is defined as the ratio opp/hyp. In this problem that ratio is
opp
------ = sin A = 13/85
hyp
We use the inverse sine function arcsin x to determine Angle A:
A = arcsin 13/85 = 8.8 degrees
Answer:
Sin(A) = [tex]\frac{13}{85}[/tex]
Step-by-step explanation:
Sin ratio = [tex]\frac{opposite}{hypotenuse}[/tex] (according to the given or asked angle)
Sin (A) = [tex]\frac{13}{85}[/tex]
Hope this helps!

A square is split into four
similar squares, one of
the new squares is split
into fourths again, and
this process continues.
What kind of sequence
does this demonstrate?
Answer:
Geometric Sequence.
Step-by-step explanation:
We are told that the square is split into 4 similar squares. One of the new squares is now split into fourths again and this same sequence is repeated over again.
This means that there is a common ratio which is ¼.
Since there is a common ratio and not common difference, this sequence is said to be a geometric sequence.
Find the length DE. Round your answer to the nearest tenth of a meter
Answer:
13.8
Step-by-step explanation:
We can use trigonometry to find the length of DE
Remember these are the trigonometric ratios
Sin = Opposite over Hypotenuse
Cos = Adjacent over Hypotenuse
Tan = Opposite over Adjacent
For ∠FDE we are given its opposite side length ( FE ) and need to find its adjacent angle ( DE )
When working with opposite and adjacent we use the trig ratio tangent
That being said we want to create an equation to solve for (DE) ( Recall that tan = opposite over adjacent. ) ( let DE = x )
so [tex]tan(51)=\frac{17}{x}[/tex]
now we solve for x
Step 1 multiply each side by x
tan(51) * x = x tan (51)
[tex]\frac{17}{x} *x=17[/tex]
now we have x tan (51) = 17
step 2 divide each side by tan (51)
[tex]\frac{xtan(51)}{tan(51)}=x\\\frac{17}{tan(51)}[/tex]
we now have
[tex]x =\frac{17}{tan(51)} \\[/tex]
[tex]tan(51)=1.234897157\\\frac{17}{1.234897157} =13.76632856[/tex]
we're left with x = 13.76632856
Finally we round to the nearest tenth and get that the answer 13.8

Alright another here we go, Please help!
Answer:
4x=y
Step-by-step explanation:
4x=y is your answer because if x is 5, like in the table, then 4(5) would equal 20, which is the y-value. It also works for every number in the table.

a ramp measures 6 feet long. if the ramp is 12 inches tall, what is the horizontal distance it covers? i'll give brainliest to whoever answers first/correctly!
we know that
1 ft--------> is equals to 12 in
the ramp is 12 inches tall----------> 1 ft tall
A ramp measures------------------> 6 ft long
applying the Pythagorean theorem
c²=a²+b²
where
c-----> 6 ft long
a----> horizontal distance
b-----> 1 ft tall
a²=c²-b²------> a²=6²-1²-----> a²=35------> a=√35------> a=5.92 ft
the answer is
5.92 ft
Answer:
6.08 or so
Step-by-step explanation:
The height is 1 foot, while the length is 6 feet.
You can use the Pythagorean Theorum to solve this, as you plug in the values.
The theorum states that A squared plus B squared = C squared, where A is the length, and B is the width. (It doesn't matter if A is the width and B is the length either.)
So if we plug in the values:
1 squared plus 6 squared = C squared.
1 + 36 = 37
Since it is C squared, we can find the square root of 37, which is something like 6.0827625302982196889996842452021.
So usually we round to the hundredths place, so we can use 6.08.

Harry pays a tv priced £1200 plus VAT 20%. He pays £300 deposit and the balance in 10 equal monthly payments calculate the monthly payment
Answer:
£114
Step-by-step explanation:
total price of the tv = cost + tax
tax = o.2 x 1200 = 240
total price = 1200 + 240 = 1440
monthly payment = 1/10 x (1440 - 300) = 114

Solve the following system of equations for x
2x-y=4
y-x=4
Answer:
What do i do???
Step-by-step explanation:
Answer:
x = 8
y = 12
Step-by-step explanation:
Given equations are -
2x - y = 4 .......(1)
-x + y = 4 ........(2)
Add both equations, we get
2x - y + (-x + y) = 4 + 4
⇒2x - y - x + y = 8
⇒x = 8
Now,
Put the value of x in equation (2), we get
y - 8 = 4
⇒y = 4 + 8
⇒y = 12
∴ we get
x = 8
y = 12
factorize:-
x³–3x²–9x–5
no links or spam answers please!
Answer:
X³ – 3x² – 9x – 5
= x³ + x² – 4x² – 4x – 5x – 5
= x²( x + 1) – 4x ( x + 1) – 5(x + 1)
= (x + 1)(x² – 4x – 5)
= (x + 1)(x² -5x + x – 5)
= (x + 1)(x – 5) (x + 1)
hence, (x +1), (x -5) and (x +1) are the factors of given polynomial .

Where can you buy a ruler that is 3 feet long?
Answer:
At a yard sale
Step-by-step explanation:
mDE = 128 and mBC = 63. Find mZA. (The figure is not drawn to scale.)
Answer:
The angle formed by the intersection of 2 secants could be found out as: 1/2 (Arc DE - arc BC)
mDE = 128
mBC = 63
=> 1/2 (128 - 63)
=> 32.5 = mZA

A circular pool has a footpath around the circumference. The equation x2 + y2 = 2,500, with units in feet, models the outside edge of the pool. The equation x2 + y2 = 3,422.25, with units in feet, models the outside edge of the footpath. What is the width of the footpath?
Answer:
8,5 feet
Step-by-step explanation:
The equation of the form
x² + y² = (r)²
Is the equation of the circumference
We have for the pool:
x² + y² = 2500 ⇒ x² + y² = (50)²
And for the outside edge of the footpath
x² + y² = 3422,25 ⇒ x² + y² = (58,5)²
So we obtain the radius of each circumference
For the outside edge of the pool r₁ = 50 feet
For the outside edge of the footpath r₂ = 58,5 feet
Then the width of the footpath is 58,5 - 50 = 8,5 feet
