Answer:
-5.875
Step-by-step explanation:
Answer:
9
Explanation:
9 root 2 = root 81 x root 2 = root 162
Root 162 = 12.7279220614
9^2 + b^2 = 12.7279220614^2
81 + b^2 = 162
b^2 = 81
Root both
B = 9
Answer:
$59768.28
Step-by-step explanation:
5.5*36=198
3.25*36=117
117*198=23166
23166*2.58= thats a big room, let alone a lot of money
The area of the sector with a radius of 20 units and a central angle of 162° is 180π unit².
<h3>What is the sector of a circle?</h3>
A sector is the portion of a circle enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger is the major sector.
The radius of the sector =20 units
Central angle subtended by sector = 162° = 162π/180 radians
As we know the area of a sector= 0.5r²α
where r is the radius and α is the central angle.
So, the area of the given sector = 0.5*20²* 162π/180
The area of the given sector = 180π unit²
Therefore, The area of the sector with a radius of 20 units and a central angle of 162° is 180π unit².

Answer:
The distance between the tree and the tower is 18.48 meters.
Step-by-step explanation:
We are given the following information in the question:
Height of tower = 30 m
Height of man = 2 m
Angle of depression = 30 degrees
We have to find the distance between the tree and the tower.
The attached image shows the scenario.
Formula:
Thus, the distance between the tree and the tower is 18.48 meters.
