Step-by-step explanation:

The relationship between triangle sides and angles can be remembered using the mnemonic SOH CAH TOA. Here, we're interested in the relationship involving the hypotenuse and the side opposite the angle:

Sin = Opposite/Hypotenuse

For a ramp 1 m high and 2 m long, we have ...

sin(x) = (1 m)/(2 m) = 1/2

x = arcsin(1/2) = 30°

The elevation angle of the ramp needs to be 30°.
