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° = [tex]\frac{BC}{AC}[/tex]
0.9659 = [tex]\frac{10}{x}[/tex]
x = [tex]\frac{10}{0.9659}[/tex]
x = 10.35 ≈ 10.4 feet
Therefore, ramp is 10.4 feet long.
