Question

Find the m A. 31
B. 12
C. 74
D. 106

Answer 1

C is my answer

Answer 2

D ∠U=106°

Explanation:

∠TRS=∠RTU=31 (corresponding angles)

Since all angles in a triangle add up to 180:

∠TRS+∠RTS+∠RST=180

31+(4x-5)+(7x+22)=180

48+11x=180

11x=132

x=12

∠RST=7x+22=7(12)+22=84+22=106

∠RST=∠U (opposite angles in a rhombus are equal)

∠U=106°
