Question

M<N = (5x) and m <l=(x+20). What is the value of X?

10
5
4
20

Solve and explain how you got your answer

Answer 1

x = 5

Explanation:

The figure shows two pairs of opposite sides parallel, so quadrilateral KLMN is a parallelogram. Angles N and L are opposite angles in a parallelogram, so their measures are equal.

m<N = m<L

5x = x + 20

4x = 20

x = 5
