Alandscaper is making a retaining wall to shore up the side of a hill. to ensure against collapse, the wall should make an angle 75â° with the ground. how far from the base of the hill is the base of a 15-foot slanted wall?

Refer to the diagram shown below.

Let x  =  distance of the base of the ladder from the base of the hill.

By definition,
sin(75°) = x/15
x = 75*cos(75°) = 3.882 ft

The distance between the base of the hill and the base of the ladder is 3.9 ft (nearest tenth)

It's true it didin't work becouse britain continued trading with it's colonies and the system hurt economies of the countries that used it
