Question
If ABCD is a cynic quadrilateral such that 12 tan and 5cos B+3=0, then cos C tan D=
Hint:
For ABCD to be a cynic quadrilateral A+C =
and B+D =
.
The correct answer is: 
Step by step solution:
Given, ABCD is a cynic quadrilateral




Now, A+C = 
Therefore, C =
-A
Thus,


Similarly, B+D = 
Therefore, D=
-B
Thus, 


Therefore, 


Hence, option(b) is the correct option.
