Examine the following survey map.

Two surveyors, A and P, stand some distance apart on the south bank of a river, looking at a tree, T, that is on the north bank of the river. Points A, P, and T form a triangle. At points A and P, there are two parallel sight lines pointing north and forming angles outside of the triangle. At point P, angle TPA is 53 degrees. The adjacent angle between PT and the northern sight line is 37 degrees. At point A, angle TAP is not labeled, and the adjacent angle formed between AT and that northern sight line is 32 degrees.

The angles of a triangle add up to 180 degrees. a+b+c=180 | Knowing any two angles, you can calculate the missing angle. |
