Question

1. What is the value of x?

Answer 1

24

Explanation:

Step 1. We know a^2 + b^2 = c^2

Step 2. a= 10, b is just b since we are solving for b, and c is 26. Now plug them in.

Step 3. 10^2 + b^2 = 26^2

Step 4. Now find each. (10^2 = 100 and 26^2 = 676)

Step 5. Plug in!! 100 + b^2 = 676

Step 6. Now SUBTRACT 100 from BOTH sides

Step 7. Now we get: b^2 = 576

Step 8. Square root both, (the square root of b^2, cancel the exponet so it's just b now.)

Step 8. the square root of 576 is 24.

Hope it helps!

Answer 2

x = 24

Explanation:

26^2 = x^2 + 10^2

x^2 = 26^2 - 10^2 = 676 - 100 = 576

x = 24
