Answer:
a) a = 60° b = 60° c = 120° d = 60°
b) a = 140° b = 20° c = 60° d = 60°
Step-by-step explanation:
a) Sum of the angles of a hexagon = (6 - 2)180 = 720
Since the hexagon is regular, c = 720/6 = 120
a and c are supplementary, so a = 180 - 120 = 60
d = 120/2 = 60
b)
sum of the angles of a nonagon = (9 - 2)180 = 1260
a = 1260/9 = 140
140 + 2b = 180
2b = 40
b = 20
c = 60 and d = 60 (This is really difficult to explain with the vertices being labeled)
I don’t really even know anymore
Answer:
4x2
Step-by-step explanation:
4x2 is the answer cause the right side is not equal
<span>area =
