The pink bar graph is 150
Y = 54.
This is really complicated to explain, but since x is 36 and the angle on the other side of the known angle is also 36, that makes y 54. Each pair of angles has to equal to 90 degrees.
Hope this helps!
Answer:
b=5√3, c=10
Step-by-step explanation:
30-60-90 triangle
c=2a
b=a√3
10x= -8x + 36
-8x -8x
———————-
2x= 36
— —
2 2
X=18
If you're trying to solve for y
-2y = 8
Divide -2 to both sides

Cancel out the -2 on the left, Divide the -2 to the 8 on the right so
y = -4
