So you would use the law of sines so set up the equation sin18/16 = sin72/x (sin 72 being the top angle) and then you cross multiply and solve from there:)
Hope this helps!

Answer:

6.0

This is trigonometry so you use SOH CAH TOA, in this case you need TOA.

tan (18) x 16 = 5.19871514 which simplifies to 6.0

Hope this is correct and helpful
