I know that M<1=5x-16 and M<8=2x+32. I must find all 8 angles in DEGREE form. However i do not know how to do that.

**Reiny**, Wednesday, January 25, 2012 at 10:35pmYou know ∠5 + ∠8 = 180

∠5 = 180 - (2x+32) = 148-2x

you also know that ∠1 = ∠5

5x - 16 = 148 - 2x

7x = 164

x = 164/7° --- I would would have expected the answer to come out "nicer".

So angle 1 = 5x-16 = 5(164/7) - 16 = 708/7

check my arithmetic, then carefully calculate the other angles.
