Question

find the square root of 25 to determine the missing side length, c.
$a^2 + b^2 = c^2$
$3^2 + 4^2 = c^2$
$9 + 16 = c^2$
$25 = c^2$
$sqrt{25}= c$
$\boxed{?} = c$

Explanation:

Step1: Recall square root of 25

The square root of a number \( x \) is a value \( y \) such that \( y^2 = x \). For \( x = 25 \), we know that \( 5^2 = 25 \), so \( \sqrt{25}=5 \).

Step2: Substitute into the equation

We have the equation \( \sqrt{25}=c \), and since \( \sqrt{25}=5 \), we can substitute to get \( c = 5 \).

Answer:

5
