Question

CosA=0.8 Then SinA =??

Answer 1

Answer:

Step-by-step explanation:

sin square A + cos square A = 1,

:. sin square A+ (0.8) square = 1,

:.sin square A + 0.64 = 1,

:. sin square A = 1 - 0.64,

:.sin square A = 1.00 - 0.64,

:. sin square A = 0.36,

( taking square root ),

:. sin A = 0.6.
