Question

The escalator rises 25° from the ground and a vertical distance of 42 feet. How much horizontal distance does the escalator cover? Round to the nearest tenth.

Answer 1

Using the trigonometric function Tangent, you should find that 42/tan25 = 90.07

Answer 2

Set up a trig ratio.
This would be a tangent ratio since we're working with adjacent and opposite.
tan 25 = 42/x
solving 42/tan25 =x
x =90.1 ft
