Answer:
Alternate interior: angle 2 and angle 13
Vertical: angle 12 and angle 15
Alternate exterior: angle 5 and angle 10
No relationship: angle 1 and angle 16
Corresponding: angle 14 and angle 16
Consecutive interior: angle 4 and angle 11
Answer:
a-b = 2a
a-b = -2b
Step-by-step explanation:
a+b = 0
Subtract b from each side
a+b - b=0-b
a = -b
a-b =
Replace a with -b
-b -b= -2b
a = -b
Divide by -1
-a =b
or replace b with -a
a - (-a)
a+a
2a
Answer: 47 degrees
Step-by-step explanation:
7x-9=4x+15 because of the vertical angle rule
7x-9=4x+15
3x=24
x= 8
So the angle 7(8)-9 = 47°
