Question

A ramp is being built next to a 4-inch high sidewalk. The
ramps angle of inclination is 10 degrees. Estimate the
length of the ramp to the nearest tenth of an inch.

Answer 1

See attachment for reply.

Answer 2

If the ramps angle of inclination is 10 degrees. The length of the ramp to the nearest tenth of an inch is: 23 inches.

Length of the ramp

Using this formula

Sin10°=4/R

Where:

R=Length of the ramp=?

Let plug in the formula

R=4/Sin10°

R=4/0.173648

R=23.04

R=23 inches (Approximately)

Inconclusion the length of the ramp to the nearest tenth of an inch is: 23 inches.
