An envelope measures 8 inches by 15 inches. A pencil is placed in
the envelope at a diagonal forming a right triangle. What is the
length of the pencil?

The length of the pencil is 17 inches.

Step-by-step explanation:

You need to do the Pythagorean theorem. For example, this is what I did, 8^2+15^2=x^2

64+225=x^2

289=x^2

the square root of 289 is 17.
