angelica won an ipad in an office raffle.the ipad screen measures 12 inches in length and 9 inches i width. find the diagonal length of the ipad screen
To find the diagonal length of the iPad screen, we can use the Pythagorean theorem, which states that the square of the hypotenuse (diagonal length) is equal to the sum of the squares of the other two sides.
In this case, the two sides are the length (12 inches) and the width (9 inches) of the iPad screen. Let's name the diagonal length as "d."
Using the Pythagorean theorem, we can write the equation as:
d² = 12² + 9²
d² = 144 + 81
d² = 225
Now, we need to find the square root of both sides to find the value of "d":
√(d²) = √(225)
d = 15
Therefore, the diagonal length of the iPad screen is 15 inches.
