Answer:</h2>
Luke does a work of 308Nm
<h2>
Step-by-step explanation:</h2>
If we have a constant force 
that acts on a body in the same direction as the displacement 
, then the work 
is defined as the product of the force magnitude 
and the displacement magnitude 
. In other words:
, which is valid for a constant force in direction of straight-line displacement.
In this problem:
Therefore:
Answer: 8 turns
Step-by-step explanation: 5 children at a time, so 5*8=40, which is the closest to 38
Answers: Angle A is 36 degrees, angle C is 54 degrees
=================================================================
Work Shown:
The angles A and C are complementary, meaning they add to 90 degrees.
(Angle A) + (Angle C) = 90
(2x-4) + (2x+14) = 90
(2x+2x)+(-4+14) = 90
4x+10 = 90
4x+10-10 = 90-10 .... subtract 10 from both sides
4x = 80
4x/4 = 80/4 ..... divide both sides by 4
x = 20
If x = 20, then,
angle A = 2x-4 = 2*20-4 = 40-4 = 36 degrees
angle C = 2x+14 = 2*20+14 = 40+14 = 54 degrees
Note how A+C = 36+54 = 90 which helps confirm our answers.
57.4/10=5.74
the answer is 5.74
