Ablock is pulled up a ramp inclined at 25 degrees. there is an applied force of 3.2 n, 20 degrees above the plans of the ramp. what is the coefficient of friction? what is the mass of the block?

hints given to us: use the angle and fa to find the sliding force
then use the equivalent triangle to find fn
then use ff and fn to find coefficient of friction.

i am lost at the equivalent triangle.
