Question

Find the measure of angle N.

Answer 1

Explanation:

The angles of that 5-sided polygon add up to equal 540 degrees. So we add up all the angles and solve for x, then plug x back in to angle N to get our answer.

17x + 4 + 10x - 10 + 18x + 6 + 90 + 90 = 540 and

45x + 180 = 540 and

45x = 360 so

x = 8

Now we'll fill 8 back in for x to get the measure of angle N:

18(8) + 6 = 150, the last option listed
