Answer:
140
Step-by-step explanation:
AEF and DFE are opposite interior angles, so they are equal to each other
you can set the equation to 2x + 60 = 3x + 20
subtract 2x from both sides: 60 = x + 20
subtract 20 from both sides: 40 = x
plug in the value of x to the equation for AEF: 2(40) + 60
you get AEF is 140
