angle of 65° with the ground and reaches a

point on the building 20 feet above the

ground. What is the length of the ladder to

the nearest foot?

the ground. What is the horizontal distance it has

traveled (to the nearest hundred feet) when it

has attained an altitude of 400 feet?

A 20-foot pole leaning against a wall reaches

a point 18 feet above the ground. What is the

angle which the pole makes with the ground
