Use the isosceles trapezoid ABCD to answer the following questions.DA. If mZA = 45°, find the measure of the angles:mLB=mLC=mLD-B. If AC = 3x - 16 and BD = 10x - 86, find x.X=

In an isosceles trapezoid, we can find symmetries in angles and side lengths.
For example, Angles A and B are congruent, i.e., they have the same measure
Angles D and C are also congruent.
