Answer:
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!
