- She wants to know how tall the building is. She knows that she is 18 feet away from the building, at an angle of 57 degrees. She finds that TAN(57) = X/18 x 1.54/1 = 27.72. The building is 27.72 feet tall.
- She wants to know what angle she's looking at the top of the pole from. She knows she is 60 feet away from the highest point of the pole, and that it is 23 feet tall. She finds that SINX = 23/60 = 22.54
- She wants to know what angle she is looking at the light from. She knows she is 17 feet away from the light when lined to the floor, and she is 38 feet away from the light itself. She finds that COSX = 17/38 = 63.43
- She wants to know what angle she is looking at the ceiling. She knows that it is 82 feet away from her eye level, and she is 10 feet away from the ceiling when lined to the floor. She finds that COSX = 10/82 = 83
- She wants to know what angle she is looking at the top of the building from. she knows that the building is 14 feet tall, and 26 feet away from her eye level. She finds that SINX = 14/26 = 32.6
