3. Fred bought an LCD TV 12 inches long. The diagonal of the LCD TV
measures 20 inches. Find the width of of the tv

Respuesta :

Answer: 16 inches

Step-by-step explanation:

To solve this question, we will use the Pythagoras theorem which will be:

Diagonal² = Length² + Width²

20² = 12² + width²

400 = 144 + width²

width² = 400 - 144

Width² = 256

Width = ✓256

Width = 16

The width of the tv is 16 inches
