It is biased because they surveyed people who were at a park, therefore they enjoy parks and would want more in the area
The answer is 7x so Im guessing it’s either C or B
See the picture attached to better understand the problem
we know that
(x+20)+∠1=180°-------> by supplementary angles
∠1=160°-x
∠1+∠2=180°--------> by supplementary angles
∠2=180-(160-x)-----> ∠2=20+x
∠2=80°------> by corresponding angles
so
20+x=80
x=80-20-------> x=60°
the answer is60°
