Answer:
A.
Step-by-step explanation:
6^(1-1) + 6^(2-1) + 6^(3-1) + 6^(4-1)
= 1 + 6 + 36 + 216
= 259.
The area formula for a parallelogram is base*height=area. Make an equation. You know the area and the height, so plug that into the equation, and you get x*18=396. Solve for x by dividing 396 by 18 and you get 22. So, the base is 22cm.
Answer:
1st angle = X
2nd angle = X + 7
3rd angle = X + 18
Then (sum. them): 3X + 25 = 180 ==> X = 51.67 degree
Therefore,
1st angle = 51.67 degree
2nd angle = 58.67 degree
3rd angle = 69.67 degree
(3,-8)
You move down from those coordinates
X stays the same while it just moves down only Y changes
