Best ResponseYou've already chosen the best response.0imagine \(\sin \theta = x\) so this thingy will become 2x^2 + x  1 = 0 do you know how to solve for x there?

Best ResponseYou've already chosen the best response.1Now we can split that into two equations 2sin θ  1 = 0 and sin θ + 1 = 0 this much understood ?

Best ResponseYou've already chosen the best response.1Solving the first one: 2sin θ  1 = 0 sin θ = 1/2 θ = 30°, 150°

Best ResponseYou've already chosen the best response.1Second: sin θ + 1 = 0 sin θ = 1 θ = 270°
