Question: how to do sohcahtoa problems?
Answer: The part of SOHCAHTOA that has both of these parts is SOH, or sin θ = opposite/hypotenuse. Use this to solve for the angle. You can check your work in Part B if you use the answer we got as the 'adjacent' side of the triangle. If you use the ladder as the hypotenuse, use CAH, or cos θ = adjacent / hypotenuse.
