Question

How do you do question 22

Answer 1

∠YXZ = 58°

Explanation:

Use the angle sum theorem and the given relations.

∠WXY +∠WXV = ∠YXV

∠WXY +(11° +3∠WXY) = 139°

4∠WXY = 128° . . . . . subtract 11°

∠WXY = 32° . . . . . . . divide by 4

Similarly, ...

∠WXY +∠YXZ = 90°

∠YXZ = 90° -∠WXY = 90° -32°

∠YXZ = 58°
