Find the value of y. Express in simplest radical form.

Answer:
11
Step-by-step explanation:
If [tex]a^{2} +b^{2}=c^{2}[/tex]
Then [tex]5^{2} + 10^{2} = y^{2}[/tex]
25 + 100 = [tex]y^{2}[/tex]
125 = [tex]y^{2}[/tex]
[tex]\sqrt{125} = \sqrt{y^{2}[/tex]
11.18 = y
11.2 = y
11 = y
(I may be wrong because I am kind of new to this stuff)
