Question

Use the Figure to determine the value of X and Y (lesson 4.1)

Answer 1

x = 100° and y = 80°

Explanation:

y = 80° because it's a vertical angle of 80°. In the figure, you can see 80° is across from y. To find x you can see that x and 80* are on line m. They are supplementary angles meaning they add up to 180°. 180°-80° is 100°

Answer 2

x=100

y=80

Explanation:

x= 180-80=100

y=80(vertical angle)
