Step-by-step 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.

$\sin\theta=\dfrac{x}{8}$

x is rise of the ramp

$x=\sin(8)\times 10\\\\x=1.39\ m$

So, the height of the ramp is 1.39 m.
