Tension rope and pulley problem

[EV33]

Homework Statement

mass 1=mass 2= 5
theta=30

Mass 1 and mass 2 are connected by a rope on a pulley. Mass 1 is on an incline of 30 degrees, and mass 2 is hanging vertically. Find the tension of

The Attempt at a Solution

mgsin(theta)= force of gravity of mass 1 down the incline

mg= weight force of mass 2

mg+mgsin(theta)=Tension


The correct answer is (g(mass1)(mass2)(1+sin(theta)))/(mass1+mass2)

Can anyone please help me uderstand how to arrive at the correct answer?
