The ramp is 38.6 feet long
What is a Right angled triangle?
This is a triangle that has one of the sides as 90°. The sides of a Right angle triangle include:
- Hypotenuse
- Opposite
- Adjacent
The hypotenuse is the longest side
The trigonometric formular associated with Right angle triangle are:
- sin θ = Opposite / Hypotenuse
- cos θ = Adlacent / Hypotenuse
- tan θ = Opposite / Adjacent
Given:
θ = 15
height covered by the inclination ( opposite ) = 10 feet
using: sin θ = Opposite / Hypotenuse
sin 15 = 10 / Hypotenuse
Hypotenuse = 10 / sin 15
Hypotenuse = 36.637 feet
Hypotenuse ( length of the ramp ) = 38.6 feet (to the nearest tenth)
lenth of ramp = 38.6 feet
