2 dimension forces - problem solving for parked car

[maryemilyw]

Problem of the day: Trying to find the formula to use for my 15 year old daughter.
A 20,000N car is parked on an incline that makes an angle of 30 degrees with the horizontal. If the maximum force the brakes can withstand is 12,000N, will the car remain at rest?
She is just learning how to pick formula and plug in the proper info.

HELP!

Just resolve the vector into it's perpendicular & parallel components. Have you done this before?
