Jessie is building a ramp for loading motorcucles ontio a trailer. the trailer is 2.8 feet off of the ground. to avoid making it too difficult to push a motorcucle up the ramp, Jessie decides to make the angle between the ramp and the ground 15 degrees. The the nearest hundredth of a foor, find the length of the ramp..

The ground, the height off the ground of the trailer, and the ramp form a right angled triangle

The ramp is the hypotenuse

sine 15 = 2.8/ramp

Ramp length = 2.8/sine 15

ramp length = 10.82 feet correct to 2 decimal places..........Answer A

-
Use the Sine function

Sine(15) = 2.8 / x

x = 2.8 / sin15
