So to find the unknown angle, you would basically take your known variables and use this formula SohCahToa. That formula is the primary trigonometric formula for right angled triangles. #1. Verify first that it is a right angled triangle before you use the formula, and it is because there is the right angled sign! #2. Choose the appropriate formula. (I choose Toa because we are given the adjacent and the hypotenuse). #3. Plug in the known variables, then take the opposite inverse. Tanx=1.9/3.2 Tanx=0.59 X=Tan Inverse X=30.6 You said round to one place so that's it, unless you want to say x is 31 degrees.
