Answer:

D ∠U=106°

Step-by-step 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°

(z+6)÷3=(2z)/4 Please solve for z

frosja888 [35]

(z + 6) / 3 = 2z / 4
this is a proportion, so we cross multiply
(3)(2z) = 4(z + 6)
6z = 4z + 24
6z - 4z = 24
2z = 24
z = 24/2
z = 12 <==
