The measures of the interior angles of a convex decagon are 21x°, 154°, 118°, 106°, 15x°, 165°, 172°, 162°, 151°, and 160°. What is the measure of the smallest interior angle?
+36916 The interior angle sum to ( n-2) * 180 = 1440
36x + 1188 = 1440
x = 7 so the two angles with 'x' in them are 147o 105o so the smallest angle is 105o
