To determine , construct a right triangle with an opposite side of 3 and a hypotenuse of 5. This is because since , then . If you recognize the Pythagorean Triple 3-4-5, you can figure out that the adjacent side is 4, and thus, . This means that .
Hence,
Just do 6 x 0.2 to reverse the division
So the answer is 1.2
I think
