Answer:
if you divided 200 by 5.50 the answer will be 36.3636363636
The answer is 90 because 360/4 (since it is a quadrilateral) is 90 degrees
X = total amount of people
80% of x = 540
.8x = 540
x = 675
There were 675 people
If you are given the measure of angle 4, then we know angle 2 is equal since it is a vertical angle. The angle of a line is 180 degrees, so subtract the measure of angle 4 (and/or 2) which will give you the angle measure for both angle 1 and 3, since those are also equal due to vertical angles. Hope that helped! :)
