Question

find the measure of angle ∠aef in the figure below. enter only the number. the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your the solution is

Explanation:

Step1: Note linear - pair property

Linear - pair angles sum to 180°.

Step2: Set up equation

Let $\angle AEF=x$. Then $x + 120^{\circ}=180^{\circ}$.

Step3: Solve for $x$

$x=180^{\circ}-120^{\circ}=60^{\circ}$.

Answer:

60
