Answer x=20, y=60 Reason First I find x using the bottom angles that equal 180 3x + 3x + (vertical angle ) 3x 9x=180 X=20 Now I find y using the top angles that equal 180 (Vertical angle) 3x + 3x + y = 180 Substitute value of x in equation 3(20) + 3(20) + y = 180 60+60 + y =180 Combine like terms to isolate y y =180-60-60 y=60
You can check your work by substituting your x and y values into the angles
