Hi Everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I am looking for some help on this question

In Triangle EFG find the value of f, if e=7.3cm g=8.7cm and angle E= 73 degrees

This question is from the lesson "Cosine Law" and from what I understand you can use the cosine law if you have all three side lengths or 2 sides and the angle between the two sides...

however, this question provides neither... how do I solve for F?
