Answer:
b. (x + 16)° + (6x − 4)° = 180°
Step-by-step explanation:
As we know that in a quadilateral the total of the opposite angles in a circle is equivalent to the 180 degrees
As seen in the attached figure
∠ROP + ∠RQP = 180 degrees
So
(x + 16)° + (6x - 4)° = 180 degrees
Hence, the correct option is b.
Therefore all the other options which are given is incorrect
