Three angles on a straight line. The first and second angles each measures 25°. What does the third angle measure?

Step-by-step explanation:

A straight line can denote half a circle, each side having . Therefore, the sum of these three angles should be . Since the first two angles both measure , we can set up the following equation and solve:

.

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
