Answer:
50.41 feet
Step-by-step explanation:
Hypotenuse = length of ladder
31 = opposite side of angle
sin(angle) = (opposite)/(hypotenuse)
sin(78) = (36)/(hypotenuse)
hypotenuse = sin(78)/ (36)
hypotenuse = 50.41 feet
length of ladder = 50.41 feet
You find the midpoint by using the formula m=(x1+x2 then divide by 2, and y1+y2 divided by 2) that’s how you find midpoint and the (5,13) 5-x1 13-y1 and so on hope this helps!
6+5+x=41
11+x=41
11+-11+x=41+-11
x=30
