Answer:
SVW
Explanation:
Since we need V in the middle of the three letters, only c and d are left. But to read an angle, you ensure the center degree(in this case, the number 4) and make the letter in the middle. You extend the center out for the other two digits, so the only choice is SVW, not WVT because T is far off, and 4 is supposed to be SVW, or WVS.
