Question

Use the figure to determine the value of X and y

Answer 1

y = 80 because of vertical angles and x = 100 because 80 + 100 = 180

Answer 2

100,80

Explanation:

The opposite angle theorem states that, : "When two lines cross four angles are created and the opposite angles are equal."

y°=80°

Now, check that , x° and y° are in one straight line. A straight line has angle of 180°. So x° and y° should sum up to 180°

x° + y° = 180°

x° + 80° = 180°

x° = 100°
