    Thank you! That was very helpful. So tan is 5/12 and sec is -13/12 ?

    If you want to, can you help me on my next question? It says solve the equation for pheta, sin=0.7782; 90 (degrees) < pheta < 180 (degrees)

    you need to use inverse sin function \[\theta = \sin^{-1} (.7782)\] use your calculator, make sure its in degree mode also it will most likely give you an answer less than 90 you will have to subtract it from 180 to get angle in 2nd quadrant
