a quadrilateral has 4 angles that add up to 360 degrees
x + 80+110+ 75 = 360
combine like terms
x + 265 = 360
subtract 265 from each side
x + 265 -265 =360 -265
x = 95
Choice C
Let's solve for h
hx = 0.5x - 9
Step 1: Divide both sides by x.
hx/x = 0.5x - 9/ x
Answer = h = 0.5x - 9/ x
M>B = 65 so arc AC = 2(65) = 130
arc ABC = 360 - 130 = 230
m<D = 1/2(230 - 130)
m<D = 1/2(100) = 50
answer
m<D = 50 first choice
