Ineed 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

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.

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

Idk idk idk idk idk idk idk idk idk
