Question

The diagram below shows scalene triangle WXY. The measure of Angle W X Y is 71mr026-2.jpg.
Triangle X W Y. Sides W Y and X Y extend to form exterior angle at point Y with a measure of 46 degrees.

Which is true about the diagram? Select two options.
Measure of angle W Y X = 46 degrees
Measure of angle Y W X = 63 degrees
Measure of angle Y W X = 134 degrees
Measure of angle Y W X = 46 degrees
Measure of angle W Y X = 134 degrees

Answer 1

Correct answers:
- Measure of angle W Y X = 46 degrees
- Measure of angle Y W X = 63 degrees

Reason: ∠WXY = 71° and ∠WYX = 46°, so by triangle angle sum ∠YWX = 180° − 71° − 46° = 63°.
