Kendra has recently purchased a 27-inch flat screen television. If the width of the screen is 22 inches, then what is the height of the television? Round to one decimal place.

Answer 1

The diagonal is the hypotenuse of a right triangle.

a^2 + b^2 = c^2

22^2 + b^2 = 27^2

484 + b^2 = 729

b^2 = 245

b = 15.65 inches
