BRAINLIEST ANSWER TO FIRST ANSWERER!!!!!
krok68 [10]

Answer:

Option C \frac{1}{2}(185\°-x\°)=76\°

Step-by-step explanation:

we know that

The measurement of the <u>exterior angle</u> is the semi-difference of the arcs it comprises

so

76\°=\frac{1}{2}(arc\ ST-arc\ XZ)

we have

arc\ ST=185\°

arc\ XZ=x\°

substitute

76\°=\frac{1}{2}(185\°-x\°)

Rewrite

\frac{1}{2}(185\°-x\°)=76\°
