Answer:
Two pairs are B,C and A,E
Step-by-step explanation:
The reasons why are because they intersect with other angles.
The common denominator of both fractions is 60.. You can convert 11/12 into 55/60 by multiplying both the numerator and denominator by 5, and you can also convert 7/20 into 21/60 by multiplying both the numerator and denominator by 3. 55/60-21/60= 34/60, simplified to 17/30.

F(6) = 6(5 - 6) = 6(-1) = -6
f(6.1) = 6.1(5 - 6.1) = 6.1(-1.1) = -6.71
f'(6) ≈ (-6.71 - (-6))/(6.1 - 6) = -0.71/0.1 = -7.1
