31. Click here Click here to select a different question. If the sides are in a ratio of 1:2:6, then x + 2x + 6x = 180 9x = 180 x = 20, Therefore the angles are 20, 2(20) = 40, and 6(20) = 120 which means the triangle is a scalene, obtuse triangle.

32. Click here Click here to select a different question. If (n – 2)180 = 2520 then divide both sides of the equation by 180 to get (n - 2) = 14 and add 2 to both sides to get 16 sides
