A radio tower is located 300 feet from a building. From a window in the building, a person determines that the angle of elevatio
DerKrebs [107]

Answer:

The tower is approximately 381 feet high.

Step-by-step explanation:

Refer to the sketch attached. The height of the tower can be found in two parts:

  • The part above the window, and
  • The part under the window.

Each part can be seen as a leg of a right triangle. The other leg is the distance between the building and the tower and is 300-feet long. The angle opposite to the leg is given.

  • The length of the upper part is 300\cdot \sin{42^{\circ}} feet.
  • The length of the lower part is 300\cdot \sin{37^{\circ}}.

The height of the tower is the sum of the two parts:

300\cdot \sin{42^{\circ}} + 300\cdot \sin{37^{\circ}} = 300(\sin{42^{\circ}}+\sin{37^{\circ}}) = 381 feet.
