2. The bottom of a ramp is placed 15 feet from the edge of a stage

Firdavs [7]

Answer:

The slope of the ramp is 1.

Step-by-step explanation:

See the diagram attached.

Here, AC = 15 ft. and ED = 5 ft. while AE = 10 ft.

Then, EC = (15 - 10) = 5 ft.

Now, considering the right triangle Δ EDC, if $\theta$ is the inclination of the ramp, then $\tan \theta = \frac{ED}{EC} = \frac{5}{5} = 1$

Hence, $\theta = 45 ^{\circ}$

Therefore, the slope of the ramp is 1. (Answer)
