Answer:
k = 10
Step-by-step explanation:
We first have to get the 3rd angle: 180 - 115 = 65
Sum of angles in a triangle = 180
65 + (4k + 5) + (6k + 10) = 180
Collect like terms
65 + 10k + 15 = 180
80 + 10k = 180
Subtract 80 from both sides
10k = 100
Divide both sides by 10
Answer: Slope between two points equation is y2-y1/x2-x1
1157 / 500
The answer is D. 3(x+4)
