A = πr²

A = 12.57 in.²

12.57 in.² ÷ 2 = 6.285 in.²

6.285 in.² + 12 in.²

Two angles are supplementary. The measure of one angle is 4 times the measure of the other angle. What is the measure of the sma
Alexus [3.1K]
ANSWER

The smaller angle is

y = 36 \degree



.EXPLANATION

Let the angles be
x \:  and \:  \: y

where y is the smaller angle.
Since they are supplementary, they will add up to 180°.


This implies that,

x + y = 180 \degree...(1)


If one angle is 4 times the other, we can then write the following equation,

x = 4y...(2)


We put equation (2) into equation (1) to get,



4y + y = 180 \degree


5y = 180 \degree


We divide through by 5 to obtain,

y = 36 \degree


This implies that,

x = 4(36)


x = 144 \degree
