Answer:
The area of the sector (shaded section) is 29.51 
.
Step-by-step explanation:
Area of a sector = (θ ÷ 360) 
where θ is the central angle of the sector, and r is the radius of the circle.
From the diagram give, diameter of the circle is 26 m. So that;
r = 
= 
= 13 m
θ = 360 - (180 + 160)
= 360 - 340
= 
Thus,
area of the given sector = 
x 
x 
= x x x 169
= 29.5079
The area of the sector (shaded section) is 29.51 .

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.
