Question

okay so for some reason my mind went completely blank and forgot how to do pathagoream theorem. so like could you tell me the steps please​

Answer 1

The formula for the pythagorean theorem is a^2 + b^2 = c^2, or in this case, leg^2 + leg^2 = hypotenuse^2. After inserting the values into the equation, you get x^2 + 9^2 = 15^2. The next step is to find the value of x, and to do so, you must evaluate the powers (9^2 = 81, 15^2 = 225) and subtract 81 from both sides of the equation. Lastly, take the square root of both sides, and you get the final answer of 12.
Hope this helps! Have a good day!

Answer 2

Answer:

12

Step-by-step explanation:

Pythag Theorem is Leg² + Leg²= Hypotenuse²

So I set it up as: x² + 9²=15²

Then solved and got: x² + 81 =225

Then I subtracted 81 on both sides and got: x² = 144

Then squareroot each side to undo the x² and got x=12
