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
feet. - The length of the lower part is
.
The height of the tower is the sum of the two parts:
feet.
Answer:
see below
Step-by-step explanation:
3r=2
We know that r must be less than 1 because we are multiplying 3 by a number and getting 2
Taking a larger number and multiplying by r and getting a smaller number means the number must be less than 1
Divide each side by 3
3r/3 = 2/3
r = 2/3
2/3 is less than 1
