Question

cosA=0.8then find the value ofsinA​

Answer 1

Answer:

CosA=8/10=Base/hypo.

So perpendicular wiil be 6

Hence sinA = perpendi. /hypo.

SinA=6/10

OR sinA = 0.6

Answer 2

Answer:

sin A = 0.6

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
