Find the length of the missing side of the triangle shown below. Round to the nearest tenth, if necessary.

Answer:
x=8in
Step-by-step explanation:
Let the unknown side=xin
Hypotenuse^2=opposite^2+adjacent^2
Hyp=17in
Opp=xin
Adj=15in
Hyp^2=opp^2+adj^2
17^2=x^2+15^2
17^2-15^2=x^2
289-225=x^2
64=x^2
x=√64
x=8in
