Question

2cos(x) - sqr of 3 = 0

Use your graphing calculator to find all degree solutions to the equation by graphing the function represented by the left side of the equation and then finding its zeros. Make sure your calculator is set to degree mode. (Enter your answer in the form a + bk, where a  [0, 360°), b is the smallest possible positive number of degrees, and k represents any integer.
?1 =  ° +  °k
?2 =  ° +  °k

(c) Use your graphing calculator to find ? if 0° ≤ ? < 360° by graphing the function represented by the left side of the equation and then finding its zeros. Make sure your calculator is set to degree mode. 
?1 =  °
?2 =  °
