Question

I need to find the letter C by itself ..I tried using decimals •Itself to get its answer but idk

A²+B²=C²
(9)²+(3)²=C²
18+9=C²
27=C²
_=C

Answer 1

ok when I was working it out for 27=c^2 my answer was c=3 square root of 3, -3 square of 3

and that was the same answer for 18+9=c^2 was the same answer as 27=c^2


(9)^2+(3)^2=c^2 the answer I got for that was c= 3 square root of 10, -3 square root of 10 I hope its right and can help you

Answer 2

The number 27 can be divided into 9 and 3. When you square root each number you get the final answer as 3 square root 3.
