Answer:

The size of a television screen is 48\ in

Step-by-step explanation:

Let

x-----> the length of the diagonal of the screen

we know that

Applying the Pythagoras Theorem

x^{2}=H^{2}+W^{2}

we have

H=38.4\ in

W=28.8\ in

substitute the values

x^{2}=38.4^{2}+28.8^{2}

x^{2}=2,304

x=48\ in

h = 4 cm
