Question

TW¯¯¯¯¯¯TW¯ is a diameter of circle XX, and TW¯¯¯¯¯¯TW¯ is parallel to UV¯¯¯¯¯UV¯.

Circle X with diameter TW and parallel chord UV.
If the measure of arc TUTU is 25°, what is the degree measure of arc UVUV?

Answer 1

We are given with
arc TU = 25

Since TW is parallel to UV, then WV = TU = 25

And since TW is the diameter,
TW = 180
Solving for UV
UV = 360 - 180 - 2(25)
UV = 130
