Answer:
Correct answer is: 7. y = 28° and x = 29° 8. y = 7 and x = 5
Step-by-step explanation:
7.
In the parallelogram, adjacent angles are supplementary and the opposite angles are the same.
According to this:
(3 y - 20) + (4 y + 4) = 180 => 7 y - 16 = 180 => 7 y = 180 + 16 => 7 y = 196
y = 196/7 = 28° => y = 28°
4 x + (2 x + 6) = 180 => 6 x + 6 = 180 => 6 x = 180 - 6 => 6 x = 174
x = 174/6 = 29° => x = 29°
8.
At the parallelogram, the diagonal is split into two equal parts.
According to this:
3 y - 3 = 2 y + 4 => 3 y - 2 y = 4 + 3 => y = 7
x - 1 = 2 x - 6 => 2 x - x = 6 - 1 => x = 5

So first u would need tto know how many hours are in a day so there are 24 hours in a day so u would do 45x72 cause there are 72 hours in 3 days.
In a triangle the midline joining the midpoints of two sides is parallel to the third side and half as long ⇒
2(3x + 2) = 2x + 20
6x + 4 = 2x + 20
6x - 2x = 20 - 4
4x = 16
x = 16/4
x = 4
midsegment = 3x + 2 = 3*4 + 2 = 12 + 2 = 14
