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°

It is not a prime number because it is divisible by 1, 3, 11 and itself, 33.
If it were just 33 and 1, it would be prime, but it has those extra factors
