Question

What is the measure of angle J in the triangle below? *Hint: Law of Sines*

Answer 1

Using the sine rules;

The equations developed;

`(15)/(sin102)=(12)/(sinJ)`

Making sinJ the subject;

`\begin{gathered} sinJ=(12sin102)/(15) \\ sinJ=0.7825 \\ J=51.49^o \end{gathered}`

Thus, the angle is 51.5 degrees.
