Angle 1 and 2 are supplementary angles and need to equal 180 degrees
so angle 1 + angle 2 = 180:
6x+50 + 4x+40 = 180
combine like terms:
10x + 90 = 180
subtract 90 from each side:
10x = 90
divide both sides by 10
x = 9
B similar AA criteria
there are two angles that measure the same and according to the AA criteria that means the two triangles are similar.
I think 12 minutes because if you take 9 divide it by 3/4 you get 12
I got:
−
8
f − 16
