A and C are supplemental
A + 43 = 180 subtract 43 from both sides
A = 137°
2.
A and C are supplemental...so...
(4x+ 5) + ( x + 15 ) = 180 simplify
5x + 20 = 180 subtract 20 from both sides
5x = 160 divide both sides by 5
x = 32
So A = 4(32) + 5 = 133°

B and D are supplemental
4x - 20 + x = 180 simplify
5x - 20 = 180 add 20 to both sides
5x = 200 divide both sides by 5
x = 40
So...B = 4(20) - 20 = 60°
