Answer:
x=[tex]\sqrt{41\\}[/tex]
Step-by-step explanation:
To do this we need to use the pythagorean theorem.
This theorem states that the a^2+b^2=c^2
where a and b are sides of the triangle and c is the hypotenuse.
This said we can set up the following expression:
4^2+5^2=c^2
Simplify.
16+25=c^2
41=c^2
c=[tex]\sqrt{41\\}[/tex]
c is what we named x, so x=[tex]\sqrt{41\\}[/tex]
