laptop screen sizes are determined by the length of the diagonal portion of the screen; rounded to the nearest whole number. a laptophas a 10 inch width and the height measures 8 inches. calculate the screen size.
To find the answer is a bit tricky but you would use 'The Pythagorean Theorem'
so the formula for this is
a2+c2=b2
(# is an exponent)
82+c2=102
82=64, 10*2=100
64xC=100
subtract 64 from 100:
C=36
then you square 36 giving you 6 as the answer!
Hope this helped!!
Answer:
The screen size to the nearest whole number is 13 inches.
Step-by-step explanation:
Consider the provided information.
The laptop has a 10 inch width and the height measures 8 inches. Screen sizes are determined by the length of the diagonal portion of the screen.
Now use the Pythagorean Theorem to find the diagonal portion:
\(a^2+b^2=c^2\)
Where a and b are the legs of the triangle and c is the diagonal.
Substitute the value of a = 10 and b = 8 in the above formula and solve for c, this will gives us the screen size.
\(10^2+8^2=c^2\)
\(100+64=c^2\)
\(164=c^2\)
\(\sqrt{164} =c\)
\(12.80 =c\)
The nearest whole number is 13.
Hence, the screen size to the nearest whole number is 13 inches.
