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°

Answer:
x = 63.9
Step-by-step explanation:
We have:
=
=> QR × sin90 = 78 × sin35
=> QR × sin90 = 44.7
=> QR = 44.7
But, we also have: +
=
<=>
+
=
<=>
= 6084 - 1998.09
=> = 4085.91
=> x = = 63.9211.. = 63.9
