OpenStudy (tkhunny):
Yes. So 100 + 96 + c + d = 360 That's a start. Now what?
OpenStudy (anonymous):
c is equal to 84 and d is equal to 80
OpenStudy (tkhunny):
Why?
OpenStudy (anonymous):
uhm i think its cause they're supplementary angles or something
OpenStudy (anonymous):

Yes, they are supplementary in pairs. You have it just right. We need more information. The measure of an inscribed angle is 1/2 the arc it intersects. This gives more information.
