Aramp 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.
approximately how long is the ramp? round to the nearest tenth.

10.35

Step-by-step explanation:

Given

Ramp leading into a building makes a 15 ^{\circ} with the ground

also end of the ramp is 10 feet from the base of the building

To find length of ramp we use trigonometry

let L be the length of the ramp

i know the answer is 3

step-by-step explanation:

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
