3(2x - 5) = 4x + 33
6x - 15 = 4x + 33
6x - 4x = 33 + 15
2x = 48
x = 48/2
x = 24
This is an inverse function, so first we have to flip x and y:
y = 2x - 6
x = 2y - 6
Now, let’s substitute 2 into the equation:
2 = 2y - 6
Solve:
8 = 2y
y = 4

You need to find the slope which is 1/4 for the first one and -3 for the second one
Answer:
112 degrees.
Step-by-step explanation:
- as we know that the three set of forces will form a triangle, by using cosine rule, we can find the required angle.
- follow the diagram in the attachment.
- by cosine rule for
,
2*10*8*cos = 
now, dividing both sides by 2*10*8,
cos = -61/160
= 112.4 degrees = 112 ( appox) ( use calculator for this cos inverse function)
