Answer:

Option (C) is correct,

when we make the circle bigger or smaller we will change its radius.

Step-by-step explanation:

 A circle with standard equation,  (x-h)^2 + (y-k)^2 = r^2 where (h, k) is the center and "r"  being the radius.

We have to determine out of given options which number of the standard equation for the circle centered at the origin changes when you make the circle bigger or smaller.

Given :  Circle centered at the origin then (h , k ) becomes (0, 0)

Thus, equation of circle becomes,

(x-h)^2 + (y-k)^2 = r^2

Substitute h = 0  and  k = 0  , we get,

\Rightarrow (x-0)^2 + (y-0)^2 = r^2

 \Rightarrow x^2 + y^2 = r^2

Since, x and y coordinates depends on radius.

Thus when we make the circle bigger or smaller we will change its radius.

Thus, option (C) is correct,

An angle measures 118° less than the measure of a supplementary angle. What is the measure of each angle
Alex787 [66]
Supplementary angles add up to 180°

x = greater supplementary angle
x - 118 = lesser angle

x + (x - 118) = 180
2x - 118 = 180
2x = 298
x = 149

x - 118
149 - 118 = 31

the angles are 31° and 149°
