You find the angle, you already have the opposite and adjacent. That angle is on a straight line with theta. Of course, a straight line, the two of them add up to 180 degrees.

tan90=16/12

It is not tan of 90. You are looking for the angle, you don't know what it is so call it alpha. tan alpha=16/12.$\alpha =\tan^{-1} (16/12)$alpha is tan inverse (16/12)

i got 53.13

Good so that angle is sharing a line with theta.$\alpha +\theta =180 degrees$

7. anonymous

so i have to take away a and got answer
