IF AB = 15 and AC =23,find the length of BC (BC has a line over it)
23 - 15 = ?
To find the length of BC, we can use the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
In this case, AB and AC form the two sides of the right triangle, and BC is the hypotenuse. So, we can write the equation:
AB^2 + AC^2 = BC^2
Given that AB = 15 and AC = 23, we can substitute these values into the equation:
15^2 + 23^2 = BC^2
225 + 529 = BC^2
754 = BC^2
To find the length of BC, we take the square root of both sides:
√754 = √(BC^2)
√754 ≈ 27.49
Therefore, the length of BC with a line over it is approximately 27.49.
