Question

Which represents the reference angle for 3pi/4?


a) 3pi/4

b) Pi/3

c) Pi/4

d) Pi/6

Answer 1

Answer:

(c) Pi/4

Step-by-step explanation:

3pi/4 = (3 x 180) / 4 = 135 degrees

135 degrees is equivalent to (180 degrees - 135 degrees) 45 degrees

45 degrees = Pi/4

Therefore, the reference angle of 3pi/4 is Pi/4

Thus, the correct option is (c) Pi/4
