By the exterior angle theorem,
(4x - 4) + 40 = 60
4x - 4 = 20
4x = 24
x = 6
As you already written, you have to use Newton's law

where F is the force, m is the mass, and a is the acceleration.
You already know the mass and the force, so you have to solve the equality for the acceleration:

plug the given values:
