Answer:
a) 6
b) 85°
c) 85°
Explanation:
In a Parallelogram, adjacent angles are supplementary.
∠S + ∠T = 180°
(4x + 10 + 7x + 9) + 95= 180
4x + 10 + 7x + 9 + 95 = 180
Combine like terms,
11x + 114 = 180
11x = 180 - 114
11x = 66
Divide both sides by 11,
x = 66 ÷ 11

b) ∠U + ∠T = 180°
∠U+ 95 = 180
∠U = 180 - 95

c) ∠S + ∠T = 180°
∠S + 95 = 180
∠S = 180 - 95
