To find the diagonal of the rectangle we have to use Pythagorean theorem!
Pythagorean theorem is used to find the length of a missing angle such as the hypotenuse or the sides a and b.
Steps to solve:
1. 12 in is the length or the base of the right triangle, and 6 in is the wide or the side a. 2. Now use the formula: a^2+b^2=c^2, and plug in the numbers! 3. 6^2+12^2=c^2, now just solve the squared numbers. 4. 36+144=c^2 5. 180=c^2 6. Find the square root of 180.
And that is you answer! If helped mark me the brainiest!!
