Question

156° is equal to

(A) \(\left(\frac{17\pi}{15}\right)^c\)

(B) \(\left(\frac{13\pi}{15}\right)^c\)

(C) \(\left(\frac{11\pi}{15}\right)^c\)

(D) \(\left(\frac{7\pi}{15}\right)^c\)

Answer 1

Correct answer is (B) \(\left(\frac{13\pi}{15}\right)^c\)

Answer 2

Step-by-step explanation:

 156 degree = 156°

 As we know that 180°  = π  Radians

 1° would be equal  to π/180 

156° would be equal to 

= 156 * π/180

 = 78 π/90

 = 39 π/45 

= 13π/15 

156° = 13π/15  Radians 

So, Correct Option (B) 13π/15  Radians
