Respuesta :

D. H=7.0
Exp:
Use the equation and rewrite to find what h equals, h= sq.rt.(d^2-w^2)
When the numbers are plugged in and you solve for H, h=7

Answer : The height of the  laptop screen is, 7.0 in

Step-by-step explanation :

As we are given that the expression as:

[tex]d=\sqrt{w^2+h^2}[/tex]

Given:

w = 11.3 in

d = 13.3 in

Now put all the given values in the above expression, we get:

[tex]d=\sqrt{w^2+h^2}[/tex]

[tex]13.3=\sqrt{(11.3)^2+h^2}[/tex]

Squaring both side, we get:

[tex](13.3)^2=(11.3)^2+h^2[/tex]

[tex](13.3)^2=(11.3)^2+h^2[/tex]

[tex]176.89=127.69+h^2[/tex]

[tex]h^2=176.89-127.69[/tex]

[tex]h^2=49.2[/tex]

[tex]h=\sqrt{49.2}[/tex]

[tex]h=7.0in[/tex]

Therefore, the height of the  laptop screen is, 7.0 in
