Putting the formula exterior angle of a triangle = the sum of 2 interior angles of a triangle.

let the angle be x;

Therefore,

80°+x = 110°

x = ( 110 - 80 )°

x = 30°

the answer on e2020 is

10

4/5

4/3

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

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
