Find the measure of
a. 71 degrees
b. 109 degrees
c. 180 degrees
d. 82 degrees

71°

Step-by-step explanation:

Given;

<A=27°

<B=82°

<T=?

We add all angles and subtract it from 180 since an interior angle adds up to 180

<A+<B+<T=180

27°+82°+<T=180

109°+<T=180

<T=180-109

<T=71°

Therefore angle T <T is equal to 71°degrees

the correct is answer is a 9-sided polygon!
