Question

Point B is on line segment AC. Given BC = 7 and AC = 11, determine the length AB.

A) 4
B) 5
C) 6
D) 7

Answer 1

To find the length of AB, subtract the length of BC from AC, giving AB = AC - BC. With BC = 7 and AC = 11, the length of AB is 4, which is answer choice A.

Step-by-step explanation:

The student has asked how to determine the length of AB given that point B is on line segment AC, BC = 7 and AC = 11. To find the length of AB, we can use the concept that the length of a line segment is the sum of the lengths of its parts. Since AC is the entire length of the line segment and BC is a part of it, subtracting BC from AC will give us AB. Therefore, AB = AC - BC.

Applying the values we have:

AB = AC - BC

AB = 11 - 7

AB = 4

The correct answer is A) 4.
