An 11 kg object moves down a 25 degree incline at a constant speed. what is the magnitude of the coefficient of friction?

I have m=11.0kg
incline = 25 deg
but i feel like I am missing one more number in order to calculate

Fg = mg
Fg = (11.0)(9.81)
Fg = 107.91 N

Sin x Fg parallel
------ = -------------
1 Fg

Sin 25.0 Fg parallel
--------- = -------------
1 107.91

Cross multiply

(107.91)sin(25) = 45.6 N
≈ 46 N

Fg = mg

Fg = 107.91 N

Sin x/1 = Fg parallel/Fg

Sin 25.0/1 = Fg parallel/107.91

Cross multiply

(107.91)sin(25) = 45.6 N
≈ 46 N
