Question

What is the measure of angle YAC if arc BY is 34 degrees?

Answer 1

Is BAC 90 degree angle?

Answer 2

Angle BAC = 90 (tangent perpendicular to radius)
angle YAC = Angle BAC -34 = 90 -34 =?

Answer 3

Can you do that from there?

Answer 4

Thank you! c: Yes, I can.

Answer 5

Welcome!

Answer 6

...Wait, isn't it not 90-34, but 90-17?

Answer 7

Why???

Answer 8

Since 34 is the measure of arc BY?

Answer 9

Yup... You're right!!!!

Answer 10

Super smart!!!!!
So, It should be like that

Angle = 90 -17 = 73
Sorry this is my first attempt to do question with arc = degree.. I should have checked before answering... I'm so sorry!!!!
