Quick comprehension check

A block weighing 10 N is placed on an incline of 20 degrees. Calculate the force of static friction acting on the block just before it starts to slide down the incline. Show all work. A 15 N box is resting on an incline of 30 degrees. Determine the force of static friction acting on the box right before it begins to slide. Show all work.
