1.)What is the hypotenuse of a triangle if legs are 20 inches long?round to the nearest whole number

A.)28
B.)29
C.)30
D.)31

I put "C" is it correct?!

no its A

A is correct.

THANKS

To find the hypotenuse of a right triangle, you can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the two legs.

In this case, the length of each leg is given as 20 inches. So, let's calculate the length of the hypotenuse using the Pythagorean theorem:

Hypotenuse^2 = leg1^2 + leg2^2
= 20^2 + 20^2
= 400 + 400
= 800

Now, to find the length of the hypotenuse, we need to take the square root of 800. Rounding this to the nearest whole number gives us 28.

So, the correct answer is A) 28, not C) 30.
