Question

Help me please help help

Answer 1

`\angle P = \angle S \Rightarrow \angle S = 42 &^\circ\\\angle Q = \angle T \Rightarrow \angle S = 86 &^\circ\\\angle R = \angle U\\`

Sum of all angles in a triangle equals 180:

`\angle R = 180 - (86 + 42) = 180 - 128 = 52`

Answer:

`U = 52 &^ \circ`
