Answer:

= 3.29

Step-by-step explanation:

Let call the length needs to be found is q

We have Law of Cosine:

q = [tex]\sqrt{r^{2} +r^{2} -2prcosP }[/tex]

= [tex]\sqrt{6^{2}+7.2^{2} -2*6*7.2*cos(27)}[/tex]

= 3.29

The length can be found using the Law of Cosines is 3.29

Answer:

We can find side RQ

Step-by-step explanation:

In order to use the Law of Cosines:

-Two sides and the angle between them must be given to find the third side

-All three sides must be given to find an angle

In this case we are given two sides(q and r) and we are given angle P which is between them. Using this information we can come to the conclusion that side RQ is the length we can find.
