In degree measure, the angles pi/3,pi/4 , and pi/2 are respectively: a. 60, 45, 90 b. 30, 45, 90 c. 45, 60, 90 d. 60, 30, 90 (all answers are in degrees)

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.

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
