Question

Find the measure of AB? using law of sines.

Answer 1

The Law of Sines states that
$\frac{ac}{ \sin(b) } = \frac{ab}{ \sin(c) }$
Therefore,
$\frac{15}{ \sin(44) } = \frac{ab}{ \sin(53) }$
Multiply both sides by sin(53):
$ab = \frac{ \sin(53) \times 15 }{ \sin(44) }$
AB = 17.25
The answer is D) 17
