Step 1:

(a)

The triangle side is and angle is

The laws of sines :

The angle is acute angle,

Recall the relation from the ambiguous case  : .

If triangle has one solution and  is an acute angle , then and

and

Substitute , in .

If triangle has one solution, then values of  are  and .

(b)

If triangle has two solutions and is an acute angle , then

Substitute the corresponding value in above formula

Divide each side by

Finally conclude that 

(c)

If triangle has no solution and is an acute angle, then

Divide each side by

Substitute and in above expression.

.

Solution:

(a)

and

(b)

(c)

.
