Answer: 69.4
Explanation:
You need to use the Pythagorean theorem, which is a²+b²=c².
A and B are the legs, and C is the hypotenuse.
So first, we substitute A and B since we know what they are:
47²+51²=c²
Then, we solve using a calculator:
2209+2601=c²
Now, add the two together:
4810=c²
To solve this equation, you have to do the opposite of a square, which is a square root, so now we will find the square root of 4810:
Square root of 4810 is 69.35416
Finally, since you are asked to round to the nearest tenth, your answer is 69.4.
