solve for a

Answer 1

x = 4

-- All angles of a triangle add up to 180° --

-- the inverse of a trianglenis equal to its opposite angle of intersection--

1) build equation

180° = 20° + (4 + 6x) + (32x + 4)

2) solve

180-20 = 4 + 6x + 32x + 4

160 = 8 + 38x

152 = 38x

152/38 = x

x = 4

verify

180 = 20 + (4 + 6x) + (32x + 4)

180 = 20 + (28) + (132)

180 = 180 so x = 4
