Answer:
Step-by-step explanation:
Corresponding parts of congruent triangles are equal.
VT = SR
8x- 17 = 15 {Add 17 to both sides}
8x = 15 + 17
8x = 32 {divide both sides by 8}
x = 32/8
x = 4
Corresponding parts of congruent triangles are equal.
∠V = ∠S = 60°
∠W = ∠U = 90°
∠T = ∠R = 2y + 20
In Δ VUT,
∠V + ∠U + ∠T = 180 {Angle sum property of triangle}
60 + 90 + 2y + 20 = 180
2y + 170 = 180
2y = 180- 170
2y = 10
y = 10/2
y = 5
