Thanks for your question!
We know the third angle in the triangle is 65 because it is a linear pair. We also know that all the angles in a triangle adds up to 180. So:
4k + 5 + 6k + 10 = 180 - 65
10k + 15 = 115
10k = 100
k = 10

Answer:
The answer is going to be coordinate plane A
Answer:
X= -1
Y= -3
Step-by-step explanation:
y=-5x-8
y=4x+1
-5x-8=4x+1
+5x. -1 +5x -1
-9=9x
-1=x
Y=4(-1)+1
-4+1
Y=-3
