Answer 1

Using similar triangles and scale factors can help determine unknown lengths in geometric problems, which is analogous to finding the length of a side of a triangle based on given ratios and context.

Step-by-step explanation:

The question presented is a classic example of using similar triangles to determine unknown sides. Similarly, when dealing with scale drawing, the scale factor is used to convert real measurements to drawing measurements. Using the provided context, it is revealed that AC is 3 times the radius R. When applying the same understanding to the given options, the context suggests that the ratio between triangle sides in similar triangles will provide the answer for side AC.

Given scale factors and ratios, the Pythagorean theorem is a common tool to find missing lengths in geometric problems. This knowledge is applied in problems such as city block calculations as well as various physics principles, including vector operations and problem solving.
