Question
![In the diagram below, if \( AB = 51 \), and \( AC = 120 \), find \( BC \).
Diagram Description:
- The diagram consists of a straight line with three points labeled \( A \), \( B \), and \( C \) in a sequence.
- The line segment \( AB \) is indicated to have a length of 51 units.
- The entire line segment \( AC \) is indicated to have a length of 120 units.
Multiple Choice Answers:
- ○ 69
- ○ 81
- ○ 71
- ○ 89
To find \( BC \), subtract the length \( AB \) from \( AC \):
\[ BC = AC - AB = 120 - 51 = 69 \]
Therefore, the correct answer is ○ 69.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4629049e-776a-488c-a468-69a57e6338b6%2F6a874c43-8b22-4f15-b98f-abad3d7e519e%2Flu35lfa_processed.jpeg&w=3840&q=75)
