Find angle y first by setting it equal to 180
With its adjacent angles. Then solve for x by triangle angles
You need to take pictures of the graph for us to answer.
Answer:

Step-by-step explanation:
We have the following equations:


If we want to add these equations, we just need to add x-terms, y-terms and independent terms.


I hope it helps you!
Answer:73. 0
Step-by-step explanation:
Radius=8.02
Tita =130
Area of sector = tita/360 x πr^2
130/360 x 22/7 x (8.02) ^2
130/360 x 22/7 x64. 3204
= 72.99
To the nearest tenth = 73.0
Data set: <span>2, 10, 10, 11, 11, 12, 12, 12, 13, 14, 14
</span>
range: 14 - 2 = 12
median: 12
lower quartile = 10
interquartile range = 4
Data set w/o outlier 2: <span>10, 10, 11, 11, 12, 12, 12, 13, 14, 14
range: 14 - 10 = 4
median: 12
lower quartile: 10.5
interquartile range = 3.5
The value that change the most by removing the outlier is A.) THE RANGE.</span>
