Question

A wheelchair ramp is 8.0 m long. The angle of inclination is 10°. Calculate the rise of

the ramp to the nearest tenth of a meter.

Answer 1

The height of the ramp is 1.39 m.

Explanation:

We have,

A wheelchair ramp is 8.0 m long

The angle of inclination is 10°

It is required to find the rise of the ramp.

Here, hypotenuse is 8 m and angle of inclination is 10°.

Using trigonometry to find it.

`\sin\theta=(x)/(8)`

x is rise of the ramp

`x=\sin(8)* 10\\\\x=1.39\ m`

So, the height of the ramp is 1.39 m.
