Question: The three angles of a triangle add up to 180 degrees. The largest angle is 5 times bigger than the smallest. The middle angle is 3 times bigger than the smallest. How many degrees is the smallest angle? Think carefully first, then make a decision:
Let x be the smallest angle. The combination of the three is x + 3x + 5x = 9x. Thus 9x = 180. So x = 20. So the answer is 20.
