Answer:
This is pythagorean theorem
Step-by-step explanation:
The Pythagorean Theorem is a tricky subject to do, but once you get the hang of it it's pretty easy.
The formula for this is C = √a^2 + b^2
Using the formula provided, we can put your information in:
65^2 = √33^2 + b^2
Now we have to find b. For that you have to square 65 and 33, add them, then square them to get your answer, which is 72.89718787. but if you round it to the nearest tenth you get 72.9.
After that you make your equation:
4225 = √1089 + 6272.64
Then square root the equation and you get the answer:
56
