Examples of Use of Corollary to Law of Tangents

Arbitrary Example $1$

Let $\triangle ABC$ be a triangle whose sides $a, b, c$ are such that $a$ is opposite $A$, $b$ is opposite $B$ and $c$ is opposite $C$.

Let $\triangle ABC$ be such that:

\(\ds a\) \(=\) \(\ds 18.4\)
\(\ds b\) \(=\) \(\ds 12.2\)
\(\ds C\) \(=\) \(\ds 42 \degrees\)

where the units of measurement of $a$ and $b$ are arbitrary.


Then:

\(\ds A\) \(=\) \(\ds 96 \degrees 50'\)
\(\ds B\) \(=\) \(\ds 41 \degrees 10'\)
\(\ds c\) \(=\) \(\ds 12.4\)
