38*g*cos theta*mu= 180N
You have one equation in two unknowns.
You need additional information.
Is the object's velocity constant? (Zero acceleration?) If so, you can write a second equation.
1. A 38kg object is traveling down the ramp and experiences a frictional force of 180N. Calculate the angle of incline and the friction coefficient between the two surfaces.
Answers: μ(mu)=0.55
Θ=28.9 degrees
But please show work and all equations/variables used.

You cant solve this without knowing more: is the object at constant speed, accelerating, or slowing down?
