Answer:
B
Step-by-step explanation:
The function's zeroes results in vertical asymptotes. As one is at x = 1 and the other at x = -2, the zeroes must be (x-1) and (x+2), which only B contains in the numerator.
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)
Answer:
first one 280 2nd one 240
Step-by-step explanation:
Step-by-step explanation:
To do this we need to calculate the slope of each side. If we can show that the slopes of the opposite sides are the same, then the opposite sides are parallel. The slopes of the opposites were the same, so ABCD is a parallelogram.
