Answer:
see explanation
Step-by-step explanation:
Since the triangles are right use trigonometric ratios to find x and y
A
sin33° = 
= 
Multiply both sides by x
x × sin33° = 2.5 ( divide both sides by sin33° )
x = 
≈ 4.590
tan33° = 
= 
Multiply both sides by y
y × tan33° = 2.5 ( divide both sides by tan33° )
y = 
≈ 3.850
B
cos72° = = 
Multiply both sides by x
x × cos72° = 6 ( divide both sides by cos72° )
x = 
≈ 19.416
tan72° = 
Multiply both sides by 6
6 × tan72° = y, thus
y ≈ 18.466
Answer:
The earth will revolve 15° and 0.0833 radian in 1 hour
Step-by-step explanation:
We know that earth revolve one round on its axis 24 hour
We know that 1 round = 360°
So earth will revolve 360° in 24 hour
So earth will revolve 
in 1 hour
Now we have to find the revolution in radian
So 
Answer:
A = 153.94 sq mi
Step-by-step explanation:
In this scenario, we would be starting from the center point and searching the area of a square since the distance in every direction would the same 7 mi. This 7-mile distance would be our radius in this scenario. We now need to use the formula for the Area of a circle to calculate the search area. This formula is the following
A = 
A = 
A = 
A = 153.94 sq mi
A total of 153.94 square miles must be searched.
