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:

Answer:
11/2
Step-by-step explanation:
5y+3=36-y
1) Subtract 3 from both sides:
5y=33-y
2) Add y to both sides:
6y=33
3) divide both sides by 6:
y=33/6
4) Simplify the fraction:
11/2
