Given an isosceles trapezoid
So, the measure of angle 1 = 49
As shown there are two parallel lines
So, angle 3 and 49 are supplementary angles
So,
[tex]\begin{gathered} m\angle3+49=180 \\ m\angle3=180-49=131 \end{gathered}[/tex]As angle 1 = angle 49
So, the measure of angle 2 = the measure of angle 3 = 131
So, the answer will be:
[tex]\begin{gathered} m\angle2=131 \\ m\angle3=131 \end{gathered}[/tex]
