:. sin (A) = 0.8320

Explanation:

To find the value of sin A, we first must determine its angle.

Since AC = 2 ; BC = 3

By using tan (O / A)

=> tan[ (BC)/(AC)]

=> tan (3/2)

To find the value of angle, use tan^-1 on your calculator

=> tan^-1(3/2)

=> 56'19' degrees.

Then, substitute A with the value found.

=> sin(56'19')

:. sin (A) = 0.8320
