If you execute not know the trig functions really well, watch this http://www.khanacademy.org/math/trigonometry/v/basic-trigonometry to answer the question, you must write under the definitions of sin(50), cos(50), tan(50) and then solve for z=then look for the answer.

You are watching: Which expression shows the value of z?
