Equilibrium applications of Newton's laws of motion III

A toboggan slides down a hill and has a constant velocity. The angle of the hill is 8.80 with respect to the horizontal. What is the coefficient of kinetic frction between the surcae of the hill and the toboggan?

So i used the formula: sum of forces(x)= cos (8.80)=0.98823
Forces (y)= sin(8.80)=0.152986
Fk=MkFn

I'm not sure on what to do after this.
Thank you!

In the inclined plane, normal reaction Fn = mg*cosθ. Find the frictional force.
To have a constant velocity frictional force should be equal to...?
