1) For the given triangles, a = 14.5m, b = 6.03m and alpha = 55.6 degrees. Find theta. Answer in units of

No picture, but use points (0,0), (5,0), (5,7) for triangle one. The x side is labeld a and the angle near the origin is alpha.

Now the second triangle is against the y side or against the side from (5,0) to (5,7). This triangles points are to make it easier are (5,0), (5,7), and say
(7,5). theta is in the angle of this second triangle near the x axis or by point (5,0). side b is the opposite of theta
