Hi I’m stuck with my maths homework, any ideas?

A small heavy box is suspended in mid air and is held in equilibrium by the tension in a light inextensible string and a horizontal force. The tension in the string is T1, where T1 = 30i + 49k. The horizontal force is F1, where F1 = pi

Find the value of p and show that the mass of the box is 5kg

Resolve forces horizontally to find p. Then vertically to find m.
