If the height of a computer screen is 7 in. & the width is 11 in. what is the length of the diagonal? Round to the nearest inch?

Answer 1

√(7^2 + 11^2) inches which is about 13 inches.

Answer 2

Apply pythagorean theorem

c = √(a^2 + b^2)
c = √(7^2 + 11^2)
c = √(170) or 13 in answer//

Answer 3

Using Pythagoras' theorem the diagonal is about 13 inches

Answer 4

sqrt (7^2 + 11^2) = sqrt 170 = 13 inches

Answer 5

Use Pythagoras. The square on the hypotenuse = sum of squares on the other two sides.

In this case, the diagonal is the hypotenuse:
7^2 + 11^2 = h^2
49 + 121 = h^2
170 = h^2
h = 13 inches

Answer 6

7 squared =49;  11 squared = 121;......49+121 = 170;....square root of 170 = 13.0384

Answer 7

Use the Pythagorean theorem: A²+B² = C² where A and B represent the sides of a right triangle, and C represents the diagonal.

7² + 11² = C²
C² = 170
C = √170
C = 13.04

C ≈ 13 inches (rounded)............ANS

Answer 8

can someone...help...???

Answer 9

d^2 = 7^2 + 11^2
--->d = ...

Answer 10

It's a 12" diagonal.
