Question

A small airplane takes off from point A and continues to climb upward in a straight line, as shown in the diagram. What is the plane’s distance from point A when it reaches point C?

A. 6,900 feet

B. 7,000 feet

C. 11,636 feet

D. 12,600 feet

E. 13,400 feet

Answer 1

12600

Explanation:

Answer 2

The distance from A to C is 12600 ft

Explanation:

We can use similar triangles to help us solve the problem.

5600 ft AC

------------- = --------------

5200 ft 5200 + 6500

5600 ft AC

------------- = --------------

5200 ft 11700

We can solve using cross products

11700* 5600 = AC *5200

65520000=5200 AC

Divide each side 5200

65520000/5200 = AC

12600 =AC
