Answer :
Answer: 37.1
Explanation: The Law of sines states that there is a proportionality between a side of triangle and its correspondent angle, i.e.:
[tex]\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}[/tex]
where:
a, b and c are sides
A, B and C are angles
In the question, there is a triangle with 27.4 as a measure of side a, angles A and C. So, it wants the side c:
[tex]\frac{a}{sinA} = \frac{c}{sinC}[/tex]
[tex]\frac{27.4}{sin(99.7)} = \frac{c}{sin(20.4)}[/tex]
c = [tex]\frac{27.4.sin(20.4)}{sin(99.7)}[/tex]
c = 37.1
The side c is 37.1
