solve for the length of the unknown side in the following right triangle. Side AB is eight side AC is 10.( AC is the hypotenuse

1 answer

To solve for the length of the unknown side, let's use the Pythagorean theorem which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Let's label the unknown side as x.

Applying the Pythagorean theorem, we have:
8^2 + x^2 = 10^2

64 + x^2 = 100

To isolate x^2, subtract 64 from both sides:
x^2 = 100 - 64

x^2 = 36

To solve for x, take the square root of both sides:
x = √36

x = 6

Therefore, the length of the unknown side is 6.
