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

Answer:
HL
Step-by-step explanation:
Answer:
Y = 15sqrt(3)/4
Z = 15sqrt(3)/2
b = 45/4
Step-by-step explanation:
Sin(60) =Z/15
sqrt(3)/2 = Z/15
Z = 15sqrt(3)/2
Sin(30) = Y/Z
½ = Y/Z
Y = ½(15sqrt(3))/2 = 15sqrt(3)/4
Cos(30) = b/Z
sqrt(3)/2 = b/Z
b = 15sqrt(3)/2 × sqrt(3)/2
b = 45/4
sqrt is square root/radical

Answer: -1.5</h3>
============================================================
Explanation:
Draw a horizontal line from W to the y axis. You should arrive somewhere between -1 and -2. While this isn't exact, it looks like we should arrive right at the middle of -1 and -2; therefore we should get to -1.5
The y coordinate of W is -1.5
Keep in mind this is based on the assumption we reach the halfway point. Unfortunately, W is not on any horizontal grid lines to be able to determine exactly where W is along the y axis.
