medals!!!!! A balloon is released and flies straight up for 6 miles, and then the wind blows it west for 4 miles. Find the distance between the balloon and the site where it was released.
You will set this up as right triangle problem and what you are solving for is the hypotenuse of the triangle.

ok its a sq root answer
yah it is a Pythagorean problem
use the formula a^2 + b^2 = c^2
52
so 4^2 + 6^2 = 16 + 36=52 great job!
but its a sq root answer so 2 sq root 5?
what are the other answer choices?
3 sq root 7
2 sq root 3
and 2 sq root 13
\[A^2+B^2=C^2\] So if C is the Hypotenuse then:\[C = \sqrt{A^2+B^2}\]
then @alyygirl you have to do the square root of 52
So you really have \[C = \sqrt{52}\]
no 2 sq root 13
You can break up the inside square root into 4 and 13 because 4 times 13 = 52 and you will have:\[\sqrt{4 \times 13}\] Since 4 is a perfect square of the number 2 and it is multiplied by 13 we can obey the rules of square roots and take the square root of 4 out of the square root sign and multiply it by only square root of 13 like so:\[\sqrt{4 \times 13} = \sqrt{2^2 \times 13} = 2\sqrt{13}\]
yep good job! @Johnbc :)
