If 5m is the radius, then multiply it by 2, then multiply it by
.
If 5m is the diameter, then just multiply it by only
.
200 * sin(243.7) ≈ - 179.29 179.29 km to the west
200 * cos (243.7) ≈ - 88.61 88.61 km to the south
X + x + x+ 21 = 180
3x = 180 - 21
3x = 159
x = 159/3
x = 53° ← the measure of <span>each of the smallest angles
53 + 21 = 74</span>° ← the measure of the largest angle
Set up two equations: one for the amount of money collected, and one for the number of tickets sold (people who attended).
Let a= adults
Let s= students
Money equation:
Ticket equation:
Now just solve the system of equations for s:
