Answer:
5.545
Step-by-step explanation:
This problem can be easily solved by using the law of cosines, which relates the lengths of the sides of a triangle to the cosine of one of its angles.
in this case, the formula can be applied in the following way
a^2 = b^2 + c^2 - 2*b*c*cos(α)
Where
a,b,c are each of the sides of the triangle,
α is the angle between sides b and c
(See attached picture)
If we use the formula we get
a^2 = (9)^2 + (6)^2 - 2*(9)(6)*cos(37°)
a^2 = 81 + 36 - 86.2526
a^2 = 30.747
a = sqrt(30.747)
a = 5.545
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.
