Use the pythagorean Theorem to find the missing side length when a=12 and c=13

b=5

Assuming the missing side is not the hypotenuse, then

b²=13²-12²=169-144=25
=>
b=√25=5

To find the missing side length using the Pythagorean Theorem, we need to apply the formula:

a^2 + b^2 = c^2

Here, we are given that a = 12 and c = 13. We need to find the length of side b.

Substituting the given values into the formula:

12^2 + b^2 = 13^2

Simplifying:

144 + b^2 = 169

Moving 144 to the other side of the equation:

b^2 = 169 - 144

b^2 = 25

Taking the square root of both sides:

b = √25

b = 5

Therefore, the missing side length (b) is 5.

To use the Pythagorean Theorem to find the missing side length, we need to recall the formula:

a^2 + b^2 = c^2

In this case, we are given a = 12 and c = 13, and we want to find the missing side length, which we'll call b.

We can substitute the given values into the formula:

12^2 + b^2 = 13^2

Simplifying, we have:

144 + b^2 = 169

To solve for b^2, we need to isolate it on one side of the equation. We can do this by subtracting 144 from both sides:

b^2 = 169 - 144

b^2 = 25

Finally, to find b, we take the square root of both sides:

b = √25

Therefore, b = 5. So, the missing side length is 5.
