Find ACD need it guys

∠ ACD = 140°

Step-by-step explanation:

Since ∠ DCE and ∠ DEC are congruent , then

∠ DCE = = = 40°

∠ ACD and ∠ DCE are adjacent and supplementary, that is sum to 180°

∠ ACD = 180° - ∠ DCE = 180° - 40° = 140°

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

47 - 90 = 43

43 - 180 = x

x = 137
