Answer 6

Oh this is timed.. hah

Answer 7

Alrighty.. So. The measure of the interior angles of either of the four angles in the polygon is 360. So you know that m<b is 90 and so is m<c as well as the other similar angles on the other side. So far you know that two of the angles equal 180, b(90) + c(90) + 180. You also see that m<a = 131. So now you know that three of the four interior angles add up to 311. Since the measure of all four angles on the inside of the polygon should equal 360, take 360 - 311 and you will get the last angle to equal 49.

Answer 8

b(90) + c(90) = 180*

Answer 9

Make sense?
