You can put this solution on YOUR website! Two sides 45 and 20; and the angle between these sides is 71 degrees. Draw the triangle. Maybe easier to say angle at A is 71 degrees, and b=45 units and c=20 units. Angle at A is opposite of side a.
You can choose b to be the BASE for the triangle, and height is  . Does this make sense? If so, you or maybe I, can continue; otherwise this is what you need to work to understand (or I to explain).
