The way I view this problem is the resultant R is making a 60 degree angle from one of the forces, The two forces are at right angle from each other and they are the x-component Rx and the y- component Ry of the resultant. If the magnitude of Rx = 4N then the angle opposite the side is 30 degrees. The Ry component can be solved using the Pythagorean theorem.
How to find the other force?Step 1
one force=4kn
resultant=8kn
degree=60
it can be solved using the Pythagorean theorem.
Step 2
R^2 = Rx^2 + Ry^2
8^2 = 4^2 + Ry^2
64 = 16 + Ry^2
Ry^2 = 64 - 16
Ry^2 = 48
Ry = 6.9282 N
Solving for the direction of Ry
Ry is 90 degrees from Rx

What’s the value of x solve the equation
-3x+4=2x-6
Answer: x=2
Step-by-step explanation:
−3x+4=2x−6
Subtract 2x from both sides.
−3x+4−2x=−6
Combine −3x and −2x to get −5x.
−5x+4=−6
Subtract 4 from both sides.
−5x=−6−4
Subtract 4 from −6 to get −10.
−5x=−10
Divide both sides by −5.x=−5−10
Divide −10 by −5 to get 2
x=2
