henry is asked to find the exact value of cos 10pi/3. his steps are shown below.

1. subtract 2pi from
10pi/3 as many times as possible:
10pi/3 - 2pi = 4pi/3
2. find the reference angle for 4pi/3 : 3pi/2 - 4pi/3 = pi/6
3. the cosine value for pi/6 is radical 3/2
4. the cosine value is positive because pi/6 is in the first quadrant.

which of the following describes henry's errors?
(following shown in picture)
