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,

\dfrac {sin \theta}{cos \theta} = tan \theta

The angle of sine can be written as below.

sin \theta = cos \theta \times tan \theta

For the angle b, the above expression can be written as,

sin (b^\circ) = cos (b^\circ) \times tan (b^\circ)

Substituting the values in the above expression, we get,

sin (b^\circ) = \dfrac {3}{4} \times \dfrac {4}{5}

sin (b^\circ) = \dfrac {3}{5}

Hence we can conclude that the angle of sine has a value of 3/5.

To know more about the angle of sine, follow the link given below.

Help my brother MK :)
Ahat [919]

Answer:

1/12 of the original amount

Step-by-step explanation:

All you need to do is multiple 1/3 (the fraction left over) by him and his friends (4).

1/3x1/4=1/12

You make 4 into 4/1 and then flip it making it 1/4 since we are dividing.

The final answer is 1/12.
