Which angle pair is congruent? 1. ∠BEC and ∠DEF
2. ∠BEA and ∠DEF
3. ∠AEF and ∠CED
4. ∠DEF and ∠CED

Step-by-step explanation:

2 because they are the same 2 lines

B) <BEA and <DEF

Step-by-step explanation:

To find a congruent angle pair, look for vertical angles. Which is <BEA and <DEF

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
