Answer:
½x = 3 + (1/6)x ......... multiply by lcd, 6
6(½x) = 6(3) + 6(1/6)x
3x = 18 + x
2x = 18
x = 9
angle 1: x
angle 2: 3x
angle 3: (x + 3x) - 32 = 4x - 32
the thing about geometry class is that there's a lot of algebra, but the GEOMETRY GIVES YOU THE EQUATION. here you need to know the 3 angles of the triangle add up to 180°, so
x + 3x + (4x - 32) = 180
8x - 32 = 180
8x = 212
x = 26.5
angle 2 = 3(26.5) = 79.5°
Hope it helps you !
