Answer 2

Answer:

A is 50° and so is B. C is the difference between 180° and 50° i.e. 130°.

Step-by-step explanation:

A is 50° as it is parallel to the angle below C. B is 50° as it is vertically opposite (and hence equal) to angle A. C is 130° as we saw that opposite angles are equal. Hence, the measure of the angle vertically opposite to the "50°" angle is also equal to 50°. And since this angle and angle C are on a straight line, angle C is the difference between 180° and 50° i.e. 150°.

Hope this helped.
