The angle of fire in the standard position will be B. 120°; 2 pi over 3 radians.
<h3>
How to calculate the angle?</h3>
It should be noted that the image shows the shooting angles arrangements. Also, π = 180°.
In this case, the value of the angle will be:
= 12π/18
= (12 × 180) / 18
= 12 × 10
= 120°
Therefore. the angle of fire in the standard position will be B. 120°; 2 pi over 3 radians.

Answer:
length = 10 ft, width = 9 ft
Step-by-step explanation:
The opposite sides are congruent
The perimeter (P) = 38 and is the sum of the 4 sides, then
15 - 2x + 15 - 2x + x + 7 + x + 7 = 38 , that is
- 2x + 44 = 38 ( subtract 44 from both sides )
- 2x = - 6 ( divide both sides by - 2 )
x = 3
Then
length = x + 7 = 3 + 7 = 10 ft
width = 15 - 2x = 15 - 2(3) = 15 - 6 = 9 ft
The equation is b-a= 21;
2b-5a = 18
a=8 and b= 29
therefore 29-8= 21
2 (29) -5 (8) = 18
58-40=18
