Question

Find the angle measure indicated. Assume that lines which appear to be tangent are tangent.

Answer 1

60°

Explanation:

I added a photo of my notes

Draw a bisector from the center of the circle and then two right triangles will be formed

Now you can find the measure of x (the sum of triangle's angles is equal to 180°):

`(0.5x)° + 90° + 60° = 180°`

`(0.5x)° = 180° - 90° - 60°`

`x = 60°`
