Aramp leading into a building makes a 15o 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.

The ramp is 10.4 ft long

Step-by-step explanation:

A rectangle triangle is formed in which the ramp is the hypotenuse, the distance between the end of the ramp and the base of the building is one of the sides (its measure is 10 ft) and the angle between this distance and the hypotenuse is 15° (let's call it angle A).

From cosine definition:

cos(A) = (adjacent side)/(hypotenuse)

hypotenuse = 10 ft/cos(15°) = 10.4 ft

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
