Answer:
x = 13
Explanation:
The first step to finding x is to apply the numbers to the Pythagorean Theorem.
The formula for the Pythagorean Theorem is a^2 + b^2 = c^2.
1. Now we have to put the known values in place of the letters.
a = 12
b = 5
c = x
2. Since the formula is squaring a, b, and c, we have to square the numbers too.
a = 12^2
b = 5^2
c = x^2
12^2, or 12 squared, is 144.
5^2, or 5 squared, is 25.
3. Next we have to add those two numbers.
144 + 25 = 169
4. Lastly, we have to square root 169
√169 = 13
Therefore, your answer is 13.
Hope this Helps!
