How Do You Calculate Tension and Angle in a Two-Mass Pulley System?

[Lovesphysics]

Homework Statement

In the figure a box of mass m1 1.0kg, on a frictionless inclined surface is connected to another box of mass m2  2.0 kg . The pulley is massless and frictionless. An upward force of magnitude F = 6.0 N acts on m2 , which has a downward acceleration of 5.5 m/s2. What are (a) the tension in the cord and (b) angle  ?
