# Isaac Physics help

I'm very stuck on this question, could someone help please?

A light string is tied to two pegs P and R, with R above and to the right of P. A mass m is attached to a point Q on the string such that the section PQ is horizontal and the section QR makes an angle of θ=30 to the horizontal.

If the system is in equilibrium, what is the tension in the section of string PQ? Please express the value of any trigonometric function as a surd.

Have you sketched it and resolved/balanced forces, or drawn a forces triangle?

They provide the following picture:
But still, I am unsure
Resolve vertically to find T_QR, then horizontally to find T_QP.
