Question 349086
the diagonal forms the hypotenuse of a right triangle.


the length is one leg of the right triangle.


the width is the other leg.


if you let:


a = 1 leg of the right triangle
b = the other leg of the right triangle
c = the hypotenuse of the right triangle


then:


c^2 = a^2 + b^2 which becomes:


c^2 = 15^2 + 8^2 which becomes:


c^2 = 225 + 64 which becomes:


c^2 = 289.


Take the square root of 289 to get:


c = 17.


You got it right.
