Question

TVs are usually measured as a diagonal distance across the screen for screen measures 15.1 inches in height and 19 inches diagonally what is the width of the screen round to the nearest 10

Answer 1

11.53 inches

Explanation:

Given data

Diagonal = 19 inches

Height= 15.1 inches

Let us apply the Pythagoras theorem

D^2= H^2+W^2

substitute

19^2= 15.1^2+W^2

361=228.01+W^2

361-228.01=W^2

132.99= W^2

W=√132.99

W=11.53 inches

Hence the width is 11.53 inches
