Answer 1

A. Sin 140 = sin(180-40) = sin 40

B. Cos 145 = cos (180-35) = -cos 35

C. Tan 170 = tan (180-10) = -tan 10

D. sin 200 = sin(180+20) = -sin 20

E. cos 215 = cos(180+35) = -cos 35

F. Tan 250 = tan(180+70) = tan 70

G. Sin 200 = sin(180+20) = -sin 20

H. Cos 323 = cos(360-37) = cos 37

I. Tan 281 = tan(360-79) = -tan 79

J. Sec 150 = sec(180-30) = -sec 30 = (-2/3)akar 3

K. csc 170 = csc (180-10) = csc 10

L. Cot 350 = cot(360-10) = -cot 10

Semoga membantu
