8x + y = 32
8(-2) + y = 32
-16 + y = 32
y = 32 + 16
y = 48
Angle 1 = 4x - 16
angle 2 = 2x + 10
4x - 16 + 2x + 10 = 90
combine like terms
6x - 6 = 90
add 6 to both sides
6x = 96
divide both sides by 6
x = 16
angle 1 = 4x - 16 = 4(16) - 16 = 48
angle 2 = 2x + 10 = 2(16) + 10 = 42
The longer sides are 20 kilometers, and the shorter sides are 13 kilometers.
(Length times width equals 260, and 20 times 2 plus 13 times 2 is 66.)
