Question

Greg stands at a horizontal distance 35 feet from the base of the building. The angle of elevation Craig stands out a horizontal distance 35 feet from the base of the building. The angle of elevation from grade to the top of the building it’s 38° what is the height of the building to the nearest foot

Answer 1

Because X is opposite of the 38° angle and 35 is adjacent to the 38° angle, you would use tan. To set up the equation you would put X over 35 and set an equal to 38(tan). Then you would multiply both sides by 35 to cancel out the 35 on the bottom of the X. When you multiply 38(tan) by 35, you get X equals 27.
