a 20ft. ladder is leaning against a wall so that the foot of the ladder is 9ft. from the buss of the wall what angle does the ladder make with the ground? what is the distance from the top of the ladder to the base of the house? based in trigonometry
Answered by Reiny
cosØ = 9/20 = .45
Ø = appr 63.3°

y^2 + 9^2 = 20^2
solve for y to get the height
