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

$76\°=\frac{1}{2}(arc\ ST-arc\ XZ)$

we have

$arc\ ST=185\°$

$arc\ XZ=x\°$

substitute

$76\°=\frac{1}{2}(185\°-x\°)$

Rewrite

$\frac{1}{2}(185\°-x\°)=76\°$
