Answer:
9
===================================================
Explanation:
The area of the parallelogram is equal to the base times height. The formula to use is A = b*h. The height and base are always perpendicular to one another.
The base is some unknown variable b. Multiply the base by the height 15 to get 15*b which is equal to the area 135
Therefore, 15*b = 135
Divide both sides by 15 and we isolate b
15b = 135
15b/15 = 135/15
b = 9
So the base is 9
Check:
area = base*height = 9*15 = 135
so the answer is confirmed
side note: we never use the value 17 at all. It is likely put in there as a distraction.

Answer:
Step-by-step explanation:
Sum of all angles of a triangle = 180
x + 64 + x + 45 + 79 = 180
Combine like terms.
2x + 188 = 180
2x = 180 - 188
2x = - 8
x = -8/2
x = -4
x + 64 = -4 + 64 = 60
x + 45 = -4 + 45 = 41
Answer:
-20
Step-by-step explanation:
-2 + -18 = -20
6). y=3
7). x=-2
I hope this helped.
