Find the measures of the numbered angles in the isosceles trapezoid.In a four-sided figure, the top and bottom sides are horizontal, the left side rises from left to right, and the right side falls from left to right. The top and bottom sides each have an arrowhead. The left and right sides each have a tick mark. In counterclockwise order from the bottom right, the angles are labeled as follows: “1,” “2,” “3,” “54 degrees.321mangle∠1= °mangle∠2= °mangle∠3=
