A loading ramp 10 feet long that makes an angle of 18 degrees with the horizontal is to be replaced by one that makes an angle of 12 degrees with the horizontal. How long is the new ramp?

The second loading ramp will have to reach the same height as the first one. We just need to know what that height is.
Without rounding we can get a more accurate measure. So, I'll use the expression in the next calculation instead of an approximation.
