can you please help me with number 3

Answer:
17in
Step-by-step explanation:
a^2+b^2=c^2 <---- formula
so...
c^2=8^2+15^2
c^2= 289 (but you only want c by its self so you need to square root it on both sides because what you do on one side you do the same on the other)
[tex]\sqrt{c^{2} }[/tex]= [tex]\sqrt{289}[/tex]
c= 17 inch
thus the answer is 17 inches
