nyatakan sudut berikut dlm ukuran derajat a. π/6° b. 7/10 π c. 11/12 π rad d. 1/4 π rad e. 7/5 π rad

a) π/6 = 180°/6 = 30°
b) 7/10 π = 7/10 × 180° = 126°
c) 11/12 π = 11/12 × 180° = 165°
d) 1/4 π = 1/4 × 180° = 45°
e) 7/5 π = 7/5 × 180° = 252°

a. π/6°=180/6= 30°
b. 7/10 π= 7/10 x 180°= 126°
c. 11/12 π rad x 180/π = 165°
d. 1/4 π rad x 180/π = 45°
e. 7/5 π rad x 180/π = 252°
