Question

a certain television is advertised as a 17 inch if the width of the tv is 8 how many inches tall is the tv

Answer 1

Answer:

15 cm

Step-by-step explanation:

Hypotenuse = 17 inch

Width = 8 inch

Let the length of the TV be x.

Using Pythagoras theorem,

(Hypotenuse)² = (Width)² + (Length)²

(17)² = (8)² + x²

289 = 64 + x²

289 - 64 = x²

x² = 225

x = √225

x = 15

Hence, length of TV = 15 cm
