Answer:
Step-by-step 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
