How to find one side of a right triangle.

Assuming you know one acute angle and the side adjacent to it, use a calculator (or a chart) to do this:

tan(angle) x adjacent = opposite

In a right triangle with an acute angle of 3deg whose adjacent side is 2.5 you’d get:

tan3 x 2.5 = .13101

    and .13101 is….. what? the other leg? which, the long, the short, or the hypotenuse?

    Quite right.

    I think I got that fixed.
