Answer:

Ramp is 10.4 feet long.

Step-by-step explanation:

Ramp AC is is making an angle of 15 with the ground BC.

The end C of the ramp is 10 feet from the base B of the building.

We have to find the length of ramp.

Let x feet is the length of the ramp.

Now Cos15° = $\frac{BC}{AC}$

0.9659 = $\frac{10}{x}$

x = $\frac{10}{0.9659}$

x = 10.35 ≈ 10.4 feet

Therefore, ramp is 10.4 feet long.
