Cosα=x/L
L=x/cosα, we are told that the ladder base is 48 ft from the base of the wall and α=39° so:
L=48/cos39 ft
L≈61.76 ft (to nearest hundredth of a foot)

Answer:
3( y - 2) + 2y =9
Step-by-step explanation:
It equals 3.
(x+108) and (x+88) are supplementary angles. This means that they add to 180.
(x+108) + (x+88) = 180
Solve for x:
2x + 196 = 180
2x = -16
x = -8
