Question

It is given that cos 0 = -0.4209 and 0° 0 < 360°. Calculato the values of 0​

Answer 1

114.89 degrees

245.11 degrees

Explanation:

cos is negative in the second and third quadrant ("pointing" on the x-axis to the left).

so, the first answer for the second quadrant is

114.89 degrees.

the answer for the third quadrant is then backwards the same angles from a full 360 degree rotation

360 - 114.89 = 245.11 degrees
