Answer:

c=0.5 cm

Step-by-step explanation:

Angle C is 15 and angle B is 105

The value of b=2cm

We need to find out 'a'

\frac{sin A}{a} =\frac{sin B}{b} =\frac{sin C}{c}

\frac{sin B}{b} =\frac{sin C}{c}

\frac{sin 105}{2} =\frac{sin 15}{c}

cross multiply it

sin(105) c= sin(15) * 2

Divide both sides by sin(105)

c=\frac{sin(15)*2}{sin(105)}

c=0.5

Answer:

c = 0.5 cm

Step-by-step explanation:

Law of sines:

sin (15) / c = sin(105) / 2

0.2588 / c = 0.9659 / 2

c = 0.2588 * 2 / 0.9659  

c = 0.5 cm
