\

Step 1:

\

$\"\"$ measures angle $\"\"$ and sides are $\"\"$ and $\"\"$ .

\

Sine rule is $\"\"$ .

\

Substitute $\"\"$ , $\"\"$ and $\"\"$ in the sine rule. \ \

\

$\"\"$ .

\

Find the length of angle $\"\"$ .

\

Consider $\"\"$ .

\

$\"\"$

\

Length of angle $\"\"$ is $\"\"$ .

\

Find the length of angle $\"\"$ .

\

$\"\"$ angle is $\"\"$ .

\

Substitute $\"\"$ and $\"\"$ in above formula. \ \

\

$\"\"$

\

Length of angle $\"\"$ is $\"\"$ .

\

Substitute $\"\"$ and $\"\"$ in the sine rule.

\

$\"\"$

\

Step 2:

\

Find length of $\"\"$ .

\

Consider $\"\"$ .

\

$\"\"$

\

Side length of $\"\"$ is $\"\"$

\

Solution :

\

Length of angles are $\"\"$ and $\"\"$

\

Side length of $\"\"$
