Question

certain television is advertised as a 17-inch TV (the diagonal length). If the width of the TV is 8 inches, how many inches tall is the TV?

Answer 1

Answer:

Draw a diagram with rectangle where 10" is the diagonal, 6" is the bottom of the screen, then you have a right triangle with hypotenuse of 10 and one side = 6.

Use Pythagorean theorm to find unknown side x;

x2 + 62 = 102                Solving for x, you get    X = 8 inches
