Answer:
3.25 in one hour
Step-by-step explanation:
6.5 ÷ 2 = 3.25
Sum of all the interior angles = (5-2)x180 = 540°
540 - 100 - 120 - 100 - 90 = 130°
So the last unknown angle in the polygon is 130°
Sum of all the adjacent angles on a straight line is 180°
Angle 1 = 180 - 130 = 50°
4+8 is 12 so yes it is correct!!!
