Answer: 161 degrees</h3>
=========================================================
Explanation:
Line AE is a tangent while line AU is a secant. The angle formed by the secant and tangent lines connects with the arcs through this formula
secant tangent angle = (larger arc - smaller arc)/2
More specifically, we can say:
angle EAI = (arc EU - arc IE)/2
42 = ( (7m+5) - (3m-1) )/2
42*2 = (7m+5) - (3m-1)
84 = 7m+5 - 3m+1
84 = 4m+6
4m+6 = 84
4m = 84-6
4m = 78
m = 78/4
m = 39/2
m = 19.5
Use this value of m to compute each arc
- arc IE = 3m-1 = 3*19.5-1 = 57.5 degrees
- arc EU = 7m+5 = 7*19.5+5 = 141.5 degrees
Let's say arc IU is some unknown number x. It must add to the other two arc measures to form 360 degrees, which is a full circle.
(arc IU) + (arc IE) + (arc EU) = 360
x + 57.5 + 141.5 = 360
x + 199 = 360
x = 360-199
x = 161
The measure of minor arc IU is 161 degrees
Weird. I think you just need to look if the point falls on the shaded area. But only (-5,5) does ...
C= Cost
g= # of times games played
C = 0.50g + 3
C(0) = 0.50(0) + 3
C(0) = 0 + 3
C(0) = 3
This means that no games have been played yet and the entrance fee is $3
The width is 10.9. When you need to find the length or width when you have the area you divide the area by given number you have so for this problem you divide 82.84 by 7.6 to get 10.9 meters.
