You cannot expect to receive any kind of meaningful help when you are THIS vague. Be specific. If this is a question regarding school work, please use the Homework, Coursework, & Textbook Questions forum. Take note of the rules for that forum before posting.

I just dont get the concept of the whole thing.
Question:
A pulley and ramp are frictionless and the black is in static equilibrium. What is the mass of the block? If the degree is 35 and has 20 kg

Draw a free body diagram (similar to the triangle of the ramp...) Use trigonometry to find the forces (you have one leg of the triangle already, and all the angles....).

When they say the system is in equilibrium, they're saying that the net force is zero: that is, all the forces cancel each other.

Since it's a static equilibrium, the block and anything else being affected by forces in the system is stationary.
