The circle below has center t. suppose that m uv = 138 degrees and that uw is tangent to the circle at u. find the following

Angle UTV is basically given: it's 138°.

Moreover, since UTV is isosceles, the other two angles have the same measure x. We thus have

So, TUV is 21°, and VUW is complementary, so it must be 69° so that they sum up to 90°

only 10/60 isn't equivalent

hope this : )
