Ryan Cherry · Answer 1

The first thing you should do for these cases is to transform radians to degrees. To do so, you must multiply all values by a factor of (180) / (pi). Making the conversion we have

(pi / 3) * ((180) / (pi)) = 60

(pi / 4) * ((180) / (pi)) = 45

(pi / 2) * ((180) / (pi)) = 90

answer

A. 60, 45, 90

Christine Snow · Answer 2

Solution : - The value of pi expressed in radians and its equivalent degree is = 180 degree Hence, the value of pi/3 = 180 / 3 = 60 deg similarly, the value of pi/3 = 180/4 = 45 deg similarly, the value of pi/2 = 180/2 = 90 deg Ans : - The angles of pi/3, pi/4, pi / 4 is = 60, 45, 90 degree respectively. Hence the right option is answer is A.
