Just before the box starts moving, according to Newton's first law, we have:
The sine of the angle (25°) of a right triangle is defined as the opposite cathetus () to that angle divided into the hypotenuse (W):

Recall that the maximum frictional force is defined as:
Replacing (3) in (1) and (4) in (2):
Replacing (7) and (6) in (5) and solvinf for :
