Question

1. find ac
2. find ac

Explanation:

Step1: Identify coordinates

Let's assume coordinates of A and C from the graph. For the first graph, if A(x1,y1) and C(x2,y2), use distance formula $d = \sqrt{(x2 - x1)^2+(y2 - y1)^2}$.

Step2: Calculate distance

Substitute values into formula. Repeat for second graph.

Answer:

(Answers will vary based on actual coordinates read from graph)
