how do i solve this?

Answer:
y = 6
Step-by-step explanation:
You solve by using the pythagorean theorem, which is:
[tex]a^{2} +b^{2} =c^{2}[/tex]
Where a and b are legs of the triangle, and c is the hypotenuse, or y in this case. So let's rearrange this equation for c:
[tex]c=\sqrt{a^{2} +b^{2} }[/tex]
Now, we can substitute in the known values and solve:
[tex]c=\sqrt{3.6^{2} +4.8^{2} } = \sqrt{36} = 6[/tex]
Therefore, the value of y is 6
Hope this helps!
