Question 211816: An architect is using the concept of similar geometric figures and a small prototype model (shown on the right below) to design a cottage. For both the model and the actual cottage, the ratio of the height to the width (excluding the roof) is 9 to 12. If the width of the actual house is 8 ft, what is its height?

Question 215232: The measure of each interior angle of a regular polygon is 11 times that of the exterior angle. How many sides does the polygon have?
I can solve this one by using the chart our teacher had us make, that calculates interior and exterior angles for several regular polygons. But is there also a mathematical way of solving this question?
Please explain.
Thank you!
