Figure below shows two trigonometric curves with equation (solid curve) y = 5 sin² (θ+30) + 2 y = 5 cos(θ+30) + 1 (dotted curve) in the interval [-160, 260].
The two graphs intersect at the points M and N in the interval [-160, 260]. Find the coordinates of M and N. (Give your final answers to 1 decimal place)
