Math Problem Statement
Consider the 668 N weight held by two cables shown below. The left-hand cable had tension T and makes an angle of θ with the wall. The right-hand cable had tension 720 N and makes an angle of 29◦ with the ceiling. What is the tension T in the left-hand cable slanted at an angle of θ with respect to the wall? Answer in units of N.

Formulas
T ⋅ sin(θ) + 720 ⋅ sin(29°) = 668
T ⋅ cos(θ) = 720 ⋅ cos(29°)
tan(θ) = sin(θ) / cos(θ)
