Solve for x in degrees. Homework Help ✎
2sin(x) = 1
cos2(x) + 4cos(x) + 4 = 0
Draw a 30°-60°-90° triangle and label the sides.
In the first quadrant, the side opposite the 30° is one-half.
In the second quadrant, the angle with sine equal to one-half is 180° − 30° or 150°.
x = 30° + 360°n or x = 150° + 360°n
Factor the equation and simplify.
There is no solution.
