Find the length of the line segment AB if A (-39), B (43).
| February 8, 2021 | education
To calculate the length of a segment, we use the formula for calculating the distance between two points A (xa) and B (xb):
AB = √ (xb – xa) ^ 2.
Moreover, taking into account that √a ^ 2 = a, we get:
AB = √ (xb – xa) ^ 2 = (xb – xa).
Let’s substitute the values into the found formula:
AB = √ (xb – xa) ^ 2 = (xb – xa) = 43 – (-39) = 43 + 39 = 82.
Answer: the length of the segment AB is 82 units.
