Answer:
Step-by-step explanation:
The angles would be supplementary
45 + 5x + 35 = 180
5x + 80 = 180
5x = 100
x = 20
To find out why they are supplementary, refer to the transversal below
∠3 = ∠7 (corresponding angles)
∠8 = 180 - ∠7 (supplementary angles)
And since ∠7 = ∠3...
∠8 = 180 - ∠3 which is why (in the problem) those two angles are supplementary (adding to 180 degrees)
Answer:
sorry this does not factor out
Step-by-step explanation:
Answer:
-4,2
Step-by-step explanation:
a reflection across the y axis means the y values stay the same and the x values change sign
X's cancel 5y = 20 y= 4 X=0
Use the communicative property of addition to switch to order and you get
13 - 5, so the answer is 8, or k = 8
OR
-5 + 13 = k
Combine like terms
8 = k
or
k = 8<span />
