4 costheta +3sintheta=5,4sintheta-3costheta=WHAT

  • trig -

    4 sin(90-theta) + 3 sintheta
    = 5.4 sintheta -3 sin(90-theta)
    7 sin(90-theta) = 2.4 sintheta
    7costheta = 2.4sintheta
    tantheta = 2.917
    theta = 71.08 degrees

    Proceed to calculate either side of the original equation.
