The answers are as follows:

What is isosceles trapezoid?

A trapezoid with its two nonparallel sides equal.

Given:

<BAD =65

As, MN is mid segment

So,

BC= 2CM

BC = 16

Now, ABCD is isosceles trapezoid

BC= AD

So, AD= 16

and, Using mid- point theorem

MN= 1/2 AB

MN = 1/2* 22

MN= x = 11

Also, co- interior angle sum is 180 in trapezium

<BAD + <BCD = 180

<BCD + 65 =180

<BCD = 115
