A budget moving company is moving your "priceless" collection of antique fridge magnets. Everything is in a crate with a mass of 42 kg (you have a fridge magnet problem!). The crate is placed on a ramp and the movers decide to increase the angle of the ramp (
θ
in degrees) until the crate starts sliding down the ramp. If the coefficient of static friction between the crate and the ramp is 0.50 and the coefficient of kinetic friction is 0.23, at what angle does the crate start to slide?

Provide your answer as a positive or negative number ONLY, with 1 decimal place (e.g. 1.2 or -1.2). Do not write the units (e.g. s or m or m/s etc.) in the answer box. Do not use scientific notation.
