Question

A flat screen TV is measured by its diagonal length. You have enough space to fit a TV that is 25 inches wide and 20 inches tall. The diagonal of the TV measures 32 inches and it is 19.2 inches tall. How wide is the TV? Can you fit the 32” TV in your space? Explain.

Answer 1

Draw a picture. This is a r triangle: Use the Pythagorean formula to solve:

32^2 = 19.2^2 + x^2

Solve for x.
