Step-by-step explanation:
The answer is ‘B’ hope this help pls add me in brianlist!
Slope is 1/2. The equation to solve it is y2-y1 / x2-x1. I hope you understand it now :)
4023/x=100/75
(4023/x)*x=(100/75)*x
4023=1.3333333333333*x
x=4023/1.3333333333333
x=3017.25
Cosα=x/L
x=Lcosα, we are told the ladder is 10ft and α=42.5 so
x=10cos42.5° ft
x≈7.37 ft (to nearest hundredth of a foot)
