or Toby takes a sheet of paper and makes a diagonal cut from one corner to the opposite corner, making two triangles. The cut he makes is 20 centimeters long and the width of the paper is 12 centimeters. What is the paper's length?

We have a right triangle and will use the Pythagorean Theorem to solve. 

 

The Pythagorean Theorem states: \(a^2 + b^2 = c^2 \), for any right triangle, where c is the hypotenuse, and a and b are legs. 

 

Substituting what we know, we have: \(20^2 = 12^2 + b^2 \)

 

Now, we have to solve for b and take the positive value. 


Can you take it from here?
