What is the value of c? A.100 B.50 C.84 D.80
2 answers:
Answer: The correct option is (C). 84.
Step-by-step explanation: We are given to find the value of c in the figure.
We know that,
in a cyclic quadrilateral, the sum of the measures of opposite angles is 180°.
We can see that in the given figure,
the angles with measure c° and 96° are opposite to each other.
Therefore, we get
Thus, the required value of c is 84.
Option (C) is CORRECT.

So there is a hole or an asymptote at x = 3 and x = -1 and we know, that answer B) is wrong.
2. Asymptotes:
We have only one asymptote at x = -1 (and hole at x = 3), thus the correct answer is A)
