Question

Find the measure of the arc or angle indicated. Assume that lines which appear tangent are tangent.

Answer 1

? = 167°

Explanation:

the measure of the secant- secant angle TUV is half the difference of the intercepted arcs, that is

`(1)/(2)` (? - 63)° = 52° ( multiply both sides by 2 to clear the fraction )

? - 63° = 104° ( add 63° to both sides )

? = 167°
