I think it is C in my personal opinion
In mathematics, patterns are expressed as equations that will help us determine projections. When you're doing experiments, you describe the relationship between two parameters by an equation. You do this by using your results. However, when you have an equation, you can use this to determine the value of one parameter with any random number of the other parameter.

Answer:
The magnitude of the resultant force is
The direction of the resultant force is from the horizontal plane
Explanation:
Generally when resolving force, if the force (F )is moving toward the angle then the resolve force will be while if the force is moving away from the angle then the resolved force is
Now from the diagram let resolve the forces to their horizontal component
So
Now resolving these force into their vertical component can be mathematically evaluated as
Now the resultant force is mathematically evaluated as
substituting values
The direction of the resultant force is evaluated as
substituting values
from the horizontal plane
Tension may be defined as the pulling power transferred
axially through a cable, string, chain, or alike one-dimensional unceasing object,
or by separately end of a rod.
To compute for tension:
Sum the moments about the pivot:
ΣM = 0 = T * 3.5m * sin37 º - 45000N * 7.0m * cos37º
tension T = 119 434 N
A force is required, because nothing would happen if there was no energy to start it.
