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)​
