please tell okkk​

Answer 1

Answer:

∠1 = 90°

∠2 = 135°

∠3 = 45°

∠4 = 45°

∠5 = 90°

Step-by-step explanation:

Assume that ∠5 = x

∠A + ∠B + ∠C = 180° (Angle Sum Property)

30° + 60° + x = 180°

90° + x = 180v

x = 180° - 90°

x = 90°

Assume that ∠1 = z

∠5 + ∠1 = 180° (Linear Pair)

90° + z = 180°

z = 180° - 90°

z = 90°

Assume that ∠3 = ∠4 = y

∠1 + ∠3 + ∠4 = 180° (Angle Sum Property)

90° + y + y = 180°

90° + 2y = 180°

2y = 180° - 90°

2y = 90°

y = 90°/2

y = 45°

Assume that ∠2 = t

∠2 + ∠3 = 180° (Linear Pair)

t + 45° = 180°

t = 180° - 45°

t = 135°

Hope it helps
