Math help...please save meeee!!!!

The height is 9.8 m/s^2 the angle between the ramp and the ground is 55 degrees.the x is the diagonal... (if that makes sense.......
The ordinary acceleration due to gravity, if you were to fall straight down, is 9.8m/s^2. This means that your speed will increase every second. A roller coaster is designed to leat you fall more slowly, to protect you from injury. Designers slow acceleration by building a ramp to slow down the ride.
The height is 9.8 m/s^2 the angle between the ramp and the ground is 55 degrees. the x is the diagonal... (if that makes sense...)

What is the acceleration down the ramp, x, to the nearest tenth?
A) 10.6 m/s^2
B) 8 m/s^2
C) 6.9 m/s^2
D) 5.6 m/s^2

(sorry for how confusing it is, I had to turn a diagram into words...)
--please explain!!!

This is a vector question.

Draw it out. It will be easier.

However the component you're interested in is 9.8m/s² * sin(55) = 8.02 m/s² (B)
