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)
8%×n=2. 2÷8/100=2×100/8=100/4=25. so the answer is 25.
d because you take the denominator of the fraction and you put it infront of the square root then you take the numerator and multiply it by the number at hand in this case 7
7b is just 7 x b and if b is 6 its just 7 x 6
which the answer is 42
