Answer:
Step-by-step explanation:
Three forces A, B and C pull on ropes tied to a ring such that ring is in equilibrium.
For the ring to be in equilibrium the force must be concurrent i.e. there line of action must be passed through a single point.
There is no net force when forces are concurrent.
When all three forces are equal then they should be at angle of to each other.

Step-by-step explanation:
Answer: √74
Step-by-step explanation: Let's start with the distance formula, shown below.
Now simply substitute the values into the formula, my work is below.
The distance between these two points is √74.
X²-6x+8=0
x²-2x-4x+8=0
x(x-2)-4(x-2)=0
(x-4)(x-2)=0
x=4 or 2
