Question

Elissa has taken up skateboarding and with the help of friends is building a ramp in her driveway. The angle of inclination is going to be 15degrees with the maximum height of four feet how long is the ramp going to be to the nearest tenth of a foot

Answer 1

`l \approx 15.455\,ft`

Explanation:

The length of the ramp is computed with the help of the following trigonometric function:

`\sin \theta = (h)/(l)`

`l = (h)/(\sin \theta)`

`l = (4\,ft)/(\sin 15^(\circ))`

`l \approx 15.455\,ft`
