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..
A. 10.82 ft
b. 2.90 ft
c. 0.72 ft
d. 10.45 ft
A. 10.82 ft
b. 2.90 ft
c. 0.72 ft
d. 10.45 ft

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
Sine(15) = 2.8 / x
x = 2.8 / sin15
