so I do tangent

by definition

tan theta = a^-1 o

how do I algebraically solve for theta

- trig -
**drwls**, Thursday, July 30, 2009 at 5:04pmDo you mean adjacent SIDE? and opposite ANGLE?

If so, use the law of sines to get the angle B that is opposite the adjacent side (b).

Let A be the angle for which you know the adjacent side length, a. Then

a/sin A = b/sin B

solve for sin B and angle B

Then use C = 180 - A - B degrees

There will be two possible values of B if obtuse angles are allowed. If so, you have been given the ambiguous side-side-angle (SSA) set of known quantities.
