Question

Please help me with math thanks

Answer 1

Answer:

1. ∠ZYW = 59°

2.∠ABD = 38° and ∠DBC = 48°

3. ∠AEB = 23° and ∠BEC = 67°

Step-by-step explanation:

1. In this question, the other side is marked as 90°

We know that in a straight line, the angle is 180°

∴180° - 90° = 90°

In this 90°, 31° should be removed.

∴∠ZYW = 59°

2. ∠DBC = 48° (Given)

∴∠ABD = 38° = 90-48°

3. x + 1 + 3x + 1 = 90°

4x + 2 = 90°

4x = 88°

x = 22°

∴∠AEB = 23° and ∠BEC = 67°
