Hey all. Below is the question I need help with and the answer is provided. If someone can show the work of how they arrived at this answer it would be greatly appreciated

The circular bar AE has a 4-m radius. Frictionless collar B is supported by cable BC and BD as shown. Cable BC exerts 60-N force on the collar B while cable BD exerts 80 N when the collar B positioned as shown (Ignore the weight of the collar B). Problem 1.1: What are the coordinates of point B: (1.88, 3.26, 1.37) m what is the unit vector from B to D?

Explanation / Answer

z = 4*sin(20 degree)= 1.37

now

4*cos(20 degree) = 3.76

y = 3.76*sin(60 degree) = 3.26

x = 3.76*cos(60 degree) = 1.88

s0

(1.88, 3.26,1.37)
