Question 316088: A ramp 8 meters long is used to reach a loading dock. The ramp makes an angle of 22 degrees with the level ground. Since it's too steep the ramp was replaced by a new ramp that was 12 meters long. What is the angle that the new ramp makes with the ground?
THANK YOU!

You can put this solution on YOUR website!
I hope this is part of a trig course, since that
is what I'd use to solve it.
tan%2822%29+=+x%2F8
.404+=+x%2F8
x+=+3.232
and, also
tan%28a%29+=+x%2F12
tan%28a%29+=+3.232%2F12
tan%28a%29+=+.2694
a+=+15.08
The new ramp makes an angle of 15.08 degrees with the ground
