What is yhe best approximation of the value of w?
a) 1.4 cm
b) 4.0 cm
c) 6.0 cm
d) 7.3 cm

B) 4.0 cm

First, we can adapt the law of sines to the notation of our triangle:

Now, we can infer from our diagram that , , and , so we can replace the values in our previous expression:

Finally, we can solve for :

Which rounds to

We can conclude that the best approximation of w is 4.0 cm
