The answer is 2 and a half. Because 18 + 6 + 6 + 3 is 33. This is because $18 to get in then $6 for one hour another $6 for an hour and $3 for an half hour.
You need to measure the angles wich means that u use a protractor if the angle is 90 degrees is a straight angle if it is below 90 degrees is acute and if it is above 90 degrees it's obtuse
83 1/3 % = 5/6 so
20 = (5/6)x
x = (6/5)(20) = 24
I believe X= -1 and Y= -9. Hope this helped!
