Need to find tension in two cables holding a 20 kg mass at equilibrium.?

Question

20 kg mass is being held by two cables. Both are at 40 degree angles with mass. Find the tension in the two cables. Mass is suspended and in equilibrium

The cable are attached to the top left and right corners of the 20 kg mass and at a 40 degree angle the the horizontal.

Answer 1

You need to define the angle with respect to the horizontal or the vertical. What is a 40 degree angle with the mass?

If the angle is with respect to the horizontal, T = mg/2 sin(40)

If with the vertical, then T = mg/2 cos(40)
