Answer:
54 degrees
Step-by-step explanation:
If these two lines are parallel, than angles 1 and 7 are supplementary.
13x+9+5x+9=180
18x+18=180
x+1=10
x=9
Angle 6 and 7 are vertical angles, so they are equal. Therefore, angle 6 is:
5x+9=5(9)+9=54
Hope this helps!!
Answer:
D
Step-by-step explanation:
y=mx+b
m = slope
b = y intercept
m = 5
b = -8
y=5x-8
Let the number be n
Part A- 2/3 + n = 2n+3
Part B- n= 2/3 -3
n= 2-9 / 3
n= -7/3 =-2.33
Four, -6 in terms of standard unit factors I NJ makes no sense
