Replace each letter for the value it's worth, so:
= 10 * -4 * 5
= -200
Answer:
Area of Shaded Region 
Area of Semicircle 

Step-by-step explanation:
Area of Shaded Region = Area of Sector - Area of Semicircle
<u>Area of Sector</u>
Radius of the sector =20cm

<u>Area of Semicircle</u>
Since AB is the diameter of the semicircle
Radius of the Semicircle=20/2=10cm
Area of semicircle

Therefore, area of Shaded Region

Area of Square =20 X 20 

Answer:
Step-by-step explanation:
The diagram illustrating the scenario is shown in the attached photo.
We would determine angle ACB by applying the tangent trigonometric ratio which is expressed as
Tan θ = opposite side/adjacent side
Taking angle ACB as the reference angle,
Tan C = 40/30 = 1.33
Angle ACB = tan^-1(1.33) = 53.1°
The bearing is calculated with respect to the northern direction. Therefore, the bearing of B from C is
180 - 53.1 = 126.9°
Answer:
no possible values is the correct answer
