What Are the values of x and y?
dem82 [27]

Answer:

y = 72.5

x = 35.

Step-by-step explanation:

First Off, Let's Divide the question.

<em><u>Let's Find the variable y : </u></em>

<em><u /></em>

there are 2 y(s), so it is 2y.

equation:   2y +35   =180.

I put 180 because A straight Line is always 180.

2y+35=180

<u><em>1. Subtract both sides. </em></u>

2y =  145

y = 72.5

<u><em>Next,Find x </em></u>

So y + y + x = 180.

We already know y, which is<u> 72.5</u>

72.5 +72.5 + x = 180

72.5 +72.5

x + 145 = 180

x =  35.

Hope This Helps!

The length of an arc of a circle is 7.34 units, and the measure of the corresponding central angle is 81°. What is the approxima
Olin [163]

The radius of the circle is 5.2 units if the length of an arc of a circle is 7.34 units, and the measure of the corresponding central angle is 81°

<h3>What is a circle?</h3>

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have:

Length of the arc of a circle:

s = 7.34 units

The measure of central angle:

θ = 81 degrees =  1.413 radians

s = rθ

r is the radius of the circle

7.34 = r(1.413)

r = 5.19 ≈ 5.2 units

Thus, the radius of the circle is 5.2 units if the length of an arc of a circle is 7.34 units, and the measure of the corresponding central angle is 81°
