Right.

need help!!!!!!

Well, if the height is 10 inches and the width is 7 inches, then the diagonal length can be determined using a little bit of math and a whole lot of imagination. Let's get calculating!

Using the Pythagorean theorem (a^2 + b^2 = c^2), we can find the diagonal length (c) by substituting the height (a) and the width (b) of the TV. So, by substituting a = 10 inches and b = 7 inches, we get:

10^2 + 7^2 = c^2
100 + 49 = c^2
149 = c^2

Now it's time for a little bit of magic... Abracadabra, alakazam! *poof*

After some mysterious calculations, the approximate diagonal length of your TV is... drumroll please... approximately 12 inches! Ta-da! Now, go ahead and enjoy your TV with its impressive diagonal length.

To find the approximate diagonal length of a TV when given the height and width, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (diagonal) is equal to the sum of the squares of the other two sides.

In this case, the height of the TV is one side of the right triangle, and the width of the TV is the other side. Let's use the variables h for the height, w for the width, and d for the diagonal length.

According to the Pythagorean theorem, we have the equation:

d^2 = h^2 + w^2

Substituting the given values, we have:

d^2 = 10^2 + 7^2
d^2 = 100 + 49
d^2 = 149

To find the value of d, we need to take the square root of both sides:

d = √149

Calculating the square root of 149 gives us approximately 12.2.

Therefore, the approximate diagonal length of the TV is 12.2 inches.
