$\huge\blue{Question}$

You want to buy a new TV. The diagonal measure of the screen is 42 inches, and the screen width is 36.6 inches. What is the screen height? Round your answer to the nearest hundredth.

Use a²+b²=c² because its the Pythagorean theorem.

______________________________________

Given values ,

Diagonal of the TV. = 42 inches.

Screen Width = 36.6 inches

______________________________________

Let the width be x .

so ,by Pythagoras theorem,

a² + b² = c²

x² + 36.6² = 42²

x² = 42²-36.6²

x² = 1764 - 1339.56

x² = 424.44

x = √424.44

x = 20.601. [approx.]

So ,the height of the TV. is 20.601.
