Solving a Trigonometry Problem with a Missing 90-Degree Angle

[Keith]

The Attempt at a Solution

I'm not sure where to start and the book doesn't show a 90 degree angle on the lower region where h meets the base. Can someone nudge me in the right direction please?[/B]

It isn't solvable unless you assume the line h meets the base at 90 degrees.

That's kinda what I was thinking. Thanks for confirming that.

All done. The answer is 3.3.
Took more time to post this thread then it did to solve. XD

Thanks again nathanael
