Question

Circle O has secants GEY and MTY meeting at Point Y. Use the given information to solve for the missing angle or arc. If the measure of arc GM is 142degree and the measure of angleY = 58.5, find the measure of arc ET.

Answer 1

Hello,

answer: m∠arc ET=25°

Y is out the circle .

y is a exterior angle of the circle.

Explanation:

m∠y=58.5°

m∠arc GM=142°

m∠arc ET=x°

m∠arc ET=25°
