Question

1. points a, b, and c are collinear. point b is between c and a. find ba if cb = 8; ca = 13 ba=□

Explanation:

Step1: Understand collinear points

Since A, B, C are collinear and B is between C and A, we have \( CA = CB + BA \).

Step2: Solve for BA

We know \( CB = 5 \) and \( CA = 13 \). Substitute into the equation: \( 13 = 5 + BA \). Then, subtract 5 from both sides: \( BA = 13 - 5 \).

Answer:

8
