Question

In the isosceles trapezoid ABCD, find m

Answer 1

answer C

Explanation:

Isosceles trapezoids have the property that opposite angles are supplementary.

Here are some needed properties of isosceles trapezoids.

<C and <D are supplementary

<A = <D

<B = <C

<D + <B = 180

<D = 110 Given

110 + <B = 180 Subtract 110 from both sides..

<B = 70

C
