Answer:
12.18
Step-by-step explanation:

To find the area of a square is Base x Height.
Triangle is 1/2 base x height.
Variable A - horizontal axis ⇒ x
Variable B - vertical axis ⇒ y
points (x, y)
A B
1) 2 , 2
2) 2 , 8
3) 4 , 3
4) 5 , 1
5) 6 , 3
6) 7 , 5
7) 8 , 6
8) 9 , 2
Mean of Variable A.
(2 + 2 + 4 + 5 + 6 + 7 + 8 + 9) ÷ 8 = 43 ÷ 8 = 5.375 OR 5.40
Mean is the average value of the data set. Add all the numbers in the data set and divide its sum by its count.
Answer:
C 27 degrees
Step-by-step explanation:
The sum of the angles of a triangle add to 180. Let x be the third angle
62+ 91 +x = 180
Combine like terms
153+x = 180
Subtract 153 from each side
153+x-153 = 180-153
x =27
