thank you buzz,
yes, i have check again that 15 is should be 1.5 if not i will not get = 0 for the second equation
i have try and i get theta = 56 and C = 0.88 using your solution,
before this i have try and get theta 46 and C=0.69
however the ans i should get is theta = 40.9 and C =1.2
Homework Statement
i have solve a engineering problem until this part I'm stuck
C cos 30 - 1.375 cosθ = 0 ----(1)
C sin 30 + 1.375 sin θ = 15 ---(2)
. i have 2 unknown C and θ, however the change to cos to sin or via versa make me lost because of my poor mathematic
