A retaurant mut intall a wheelchair ramp. The ramp mut raie three feet. Looking up the rule online, the ramp mut be inclined no more than 5°. How many feet of wood mut the retaurant buy to rie thi ditance?



Answer :

The hypotenuse Or the distance of the wooden ramp should be 0.26 feet.

What are trigonometric ratios in terms of a right-angle triangle?

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

Given, A restaurant installed a wheelchair ramp with a height of 3 feet and the angle it makes with the distance of the ramp is no more than 5°.

Now, The height of the ramp can be thought of as the opposite and the distance of the ramp can be thought of as the hypotenuse.

Therefore, sin5° = opposite/hypotenuse.

0.087 = 3/hypotenuse.

hypotenuse = 3×0.087.

hypotenuse = 0.261 feet Or 0.26 feet.
