Step 1:

\

$\"\"$ measures angle is $\"\"$ and side $\"\"$ .

\

Draw the diagram of $\"\"$ .

\

$\"\"$

\

Observe the diagram,

\

Here, side lengths are $\"\"$

\

Consider the right angle traingle, it can be shown $\"\"$ .

\

Sine rule is $\"image\"$ .

\

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

\

$\"\"$

\

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

\

Substitute $\"\"$ in $\"image\"$ .

\

$\"\"$

\

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

\

Step 2:

\

Find length of $\"\"$ .

\

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

\

$\"\"$

\

Consider,

\

$\"\"$

\

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

\

Find length of $\"image\"$ .

\

Consider,

\

$\"\"$

\

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

\

Solution :

\

Length of angle is $\"\"$ .

\

Side lengths are $\"\"$ .
