Respuesta:
a = 82; b 164
Explicación paso a paso:
a = 1 / 2b - - - (1)
a gana 66 = a + 66
b = b - 90
a = 2b
a + 66 = 2 (segundo - 90) - - - (2)
Ponga a = 1 / 2b en (2)
1 / 2b + 66 = 2 (b-90)
0.5b + 66 = 2b - 180
0.5b - 2b = - 180 - 66
-1,5b = - 246
b = 164
a = 1 / 2b
a = 1/2 * 164
a = 82

the value of x?

Answer:
82°
Step-by-step explanation:
That is the correct answer to put it simply
The measure of x from the quadrilateral inscribed inside the circle is given by x = 82°
What is a Circle?A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
The equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
Given data ,
Let the circle be represented as P
Now , the quadrilateral inscribed inside the circle be ABCD
where the measure of m∠A = 98°
The measure of m∠B = 90°
Now , the opposite angles of a quadrilateral inscribed inside a circle are supplementary
So , measure of ∠A + measure of ∠C = 180°
On simplifying , we get
98° + x° = 180°
Subtracting 98° on both sides , we get
x = 180° - 98°
x = 82°
Therefore , the measure of x is 82°
Hence , the value of x of the quadrilateral inside circle is 82°

Use what you know about similarity and proportions to solve for x in the triangles below. Show all work.

x + 5
Answer:
Value of x = 7.5 unit
Length of side = 12.5 unit
Step-by-step explanation:
Given that both triangles are similar because all angles are equal;
So, the ratio of similar lines is in the same proportion.
[x + 5] / 5 = 10 / 4
4[x + 5] = 50
4x + 20 = 50
4x = 50 - 20
4x = 30
x = 30 / 4
x = 7.5
So,
Value of x = 7.5 unit
Length of side = x + 5
Length of side = 7.5 + 5
Length of side = 12.5 unit

Calculate the surface area of the following prism
I will give brainliest too
In case you need formula :
Total area of the lateral faces + 2 x base area = perimeter of the base x height + 2 x base area
Answer:
63sq. meters
Step-by-step explanation:
The Surface area of the pyramid = 2B + ph
Base area B = 1/2 * 2 * 1.5
B = 1 * 1.5
B = 1.5m²
Perimeter of the base = 2 + 1.5 + 2.5
p = 6m
Height of the priscm = 10m
Substitute into the formula;
TSA = 2(1.5) + 6(10)
TSA = 3.0 + 60
TSA = 63sq. meters
Hence the surface area is 63sq. meters

Answer:
C = 12 pi
Step-by-step explanation:
The radius is 6
The circumference is given by
C = 2 * pi *r
C = 2 * pi *6
C = 12 pi
Answer:
12π
Step-by-step explanation:
the circumference of the circle can be found using the formula: 2πr.
RW is the radius, and we know that RW=6, so we can plug this into the formula:
C=2πr
C=2π(6)
C=12π
so, the circumference of the circle is 12π.
Find the measures of the interior angles of the triangle
Answer:
45°, 110° & 25°
Step-by-step explanation:
We know,
x + 25° + x +65° = 180° (∵Sum of all interior angles of a triangle is 180)
or, 2x + 90 = 180°
or, 2x = 90°
∴ x = 45°
Now,
∡A = x° = 45°
∡B = x +65° = 45° + 65° = 110°

Peralta and Amy worked last winter shovelling their neighbour's driveway. Amy earned $8 more than twice the amount earned by Peralta. If their earnings totalled $110, how much did Amy earn? Use an algebraic equation to solve this problem.
Answer:
$76
Step-by-step explanation:
Peralta and Amy worked last winter shovelling their neighbour's driveway.
Let the amount
Peralta earns = x
Amy earns = y
Amy earned $8 more than twice the amount earned by Peralta.
y = 2x + $8
y = 2x + 8
If their earnings totalled $110,
x + y = 110
x = 110 - y
We substitute 110 - y for x
Hence:
y = 2(110 - y) + 8
y = 220 - 2y + 8
Collect like terms
y + 2y = 220 + 8
3y = 228
y = 228/3
y = 76
Since, the amount Amy earns = y
Therefore, Amy earned $76

What is 200 percent more than $7.50?
Answer:
200% of 7.50 is 15.00
200% more than 7.50 is 15 + 7.5 = 22.50
Step-by-step explanation:
100% of 7.50 is 7.50
another 100% is 7.50
so 200% is 15.00
200% of a value is the value multiplied by 2
200% more than 7.50 is 15.00 + 7.50 = 22.50
The value of 200% more than $7.50 is,
⇒ $22.50
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
