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:


d=√(w^2+h^2)

Given:

w = 11.3 in

d = 13.3 in

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


d=√(w^2+h^2)


13.3=√((11.3)^2+h^2)

Squaring both side, we get:


(13.3)^2=(11.3)^2+h^2


(13.3)^2=(11.3)^2+h^2


176.89=127.69+h^2


h^2=176.89-127.69


h^2=49.2


h=√(49.2)


h=7.0in

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