Answer:
120 degrees and 330 degrees
Step-by-step explanation:
Solve each equation for 0 degrees < x < 360 degrees.
Sqrt 2 cos x + 1 = 0
A.45,315
B.115,245
C.135,225
D.46, 314
Please Help ASAP!
Given the expression √(2cosx+1) = 0
Square both sides of the equation;
√(2cosx+1) = 0
2cosx + 1 = 0
2cosx = -1
cos x = -1/2
x = cos^-1(-1/2)
x = -60 degrees
Since cos is negative in the 2nd and 3rd quadrant then;
x = 180-60 = 120 degrees (2nd quadrant)
x = 270+60 = 330 degrees (3rd quadrant)
