Answer:
Same-side Interior Angles theorem justifies ∠ 11 + ∠ 10 =180°
Step-by-step explanation:
To Prove:
∠ 11 + ∠ 10 =180°
Proof:
Consider lines are Parallel,then
Corresponding Angles are Equal
∴ ∠ 10 = ∠ 12 say (equation 1)
Now by Linear Pair postulate we have,
∴ ∠ 11 + ∠ 12 = 180° say (equation 2)
Now by replacing ∠12 by ∠ 10 from equation 1 in equation 2 we get
∴ ∠ 11 + ∠ 10 = 180°
Hence proved the above statement.
Answer:
Step-by-step explanation:
The image on the right is not the answer. It is reflected across the y axis. equations and the inverses are reflections of each other across the line y = x. So that lets out the middle one as well which looks to be reflected across y = - x
That only leaves the left image which is the correct answer.
Answer:
13
Step-by-step explanation:
2x+2-3x-15>0
-x+13>0
-x>0-13
x>-13/-1
x>13
Since x = 2
6(2) = 12/4
12/4 = 3
Answer:
128
Step-by-step explanation:
X is a corresponding parallel angle, the angle opposite it which is 128 would be the same because they are parallel angles.
