Question

Please help I don't understand how to do this

Answer 1

m<B=m<K=100

m<A=m<J=133

m<L=m<C=41

m<M=m<D=86

Explanation:

Since
`ABCD\cong JKLM`, the corresponding angles are congruent.

This implies that:

`m\angle A=133=m\angle J`

m<L=41=m<C

m<M=86=m<D

The sum of angles in a quadrilateral is 360 degrees.

m<B+133+41+86=360

m<B+260=360

m<B=360-260

m<B=m<K=100
