I bought a used car at 50%-off sale. I didn't drive it much, so I sold it for 50% more than I paid for it. When I missed having "wheels," I bought the car back at 50% less than I sold it for. Soon gas was costing too much, so I sold the car again for 50% more than I paid for it the second time. Now I am confused, so I hope you can help. What percent of my original investment did I make or lose?

answer:

24pi or letter c

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.

where is the graph, sweetheart?
