Step 1:

$\"\"$ measures angles are $\"image\"$ and $\"image\"$ and side $\"image\"$ .

Substitute $\"image\"$ , $\"image\"$ and $\"image\"$ in the sine rule from (a).

$\"image\"$

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

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

$\"\"$ \ \

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

Step 2:

Find length of $\"image\"$ .

$\"\"$

Find length of $\"image\"$ .

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

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

$\"\"$

$\"\"$ \ \

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

Solution :

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

Sides is lengths are $\"image\"$ and $\"image\"$ .
