The angle of sine has a value of 3/5.
Option A is the correct representation of angle sin(b°).
<h2>How do you calculate the angle b for sine?</h2>Given that tan(b°) = 3/4 and cos(b°) = 4/5.
In trigonometry, we know that,
The angle of sine can be written as below.
For the angle b, the above expression can be written as,
Substituting the values in the above expression, we get,
Hence we can conclude that the angle of sine has a value of 3/5.
