Question

Find the measure of angle N.

A. 150°

B. 8°

C . 90°

D. 294°

Answer 1

`\angle N=150\degree`

Explanation:

The sum of interior angles of a 5-sided polygon is 540 degrees.

We sum all the angles to get:

<M+<L+<N+<O+<P=540

90+90+(17x+4)+(18x+6)+(10x-10)=540

45x+180=540

45x=540-180

45x=360

x=8

N=18*8+6

`\angle N=150\degree`
