Answer:
48%
Step-by-step explanation:
This is a very simple problem of finding percentage.
To find percentage of people preferring pizza, we need to divide "number of person who like pizza" by the "total number of person".
So, that's
240/500
And then we need to multiply by 100 and tag a "%" sign at the end. So let's do this:

So 48% of the people chose pizza.
Answer:
2x +5x-20+3x=180(angle of triangle)
10x-20=180
10x=180+20
10x=200
x=200/10
x=20
