A ramp leading into a building makes a 15° angle with the ground. The end of the ramp is 10 feet from the base of the building.
Paul [167]

Answer:

10.4feet

Step-by-step explanation:

The set up wil form a right triangle

Length of the ramp is the hypotenuse

The length of the end of the ramp from the base= 10 feet (adjacent)

Angle of elevation = 15 degrees

Required

Length of the ramp

Using SOH CAH TOA

Cos  theta = adj/hyp

cos 15 = 10/L

L = 10/cos15

L = 10/0.9659

L = 10.35

L ≈ 10.4 feet

Hence the length of the ramp is 10.4feet
