Angelica won an iPad in an office raffle. The iPad screen measures 12 inches in length and 9 inches in width. Find the diagonal length of the iPad screen
Units: inches
To find the diagonal length of the iPad screen, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the diagonal) is equal to the sum of the squares of the lengths of the other two sides.
In this case, the length (12 inches) and the width (9 inches) of the iPad screen form the two sides of the right triangle.
Let's represent the length as side a, the width as side b, and the diagonal as side c.
According to the Pythagorean theorem, we have:
a^2 + b^2 = c^2
Substituting the values, we get:
12^2 + 9^2 = c^2
144 + 81 = c^2
225 = c^2
To find c (the diagonal), we need to take the square root of both sides:
√225 = √c^2
15 = c
Therefore, the diagonal length of the iPad screen is 15 inches.
wrong
I apologize for the incorrect answer. Let's redo the calculation correctly.
We need to use the Pythagorean theorem to find the diagonal length.
Using the formula a^2 + b^2 = c^2, where a = width, b = length, and c = diagonal length:
9^2 + 12^2 = c^2
81 + 144 = c^2
225 = c^2
To find c (the diagonal length), we need to take the square root of both sides:
√225 = √c^2
15 = c
Therefore, the diagonal length of the iPad screen is 15 inches.
it is not 15 inches.
Apologies for the confusion. Let's redo the calculation correctly.
To find the diagonal length of the iPad screen, we can use the Pythagorean theorem.
Using the formula a^2 + b^2 = c^2, where a = width, b = length, and c = diagonal length:
9^2 + 12^2 = c^2
81 + 144 = c^2
225 = c^2
Taking the square root of both sides, we find:
√225 = √c^2
15 = c
Therefore, the diagonal length of the iPad screen is 15 inches.
