Answer:
You add them together to get 75 degrees then you take 180-75 to get 105 so you will subtract the sum of the two given angles from 180°. So your answer is 105 degrees.
Step-by-step explanation:
1st number = x-5
2nd number = x
3rd number = 3x-15
Total = 80
x-5+x+3x-15=80
5x-20=80
5x=100
x=20
The numbers are 20, 15, 45

I believe this would be the correct answer. When you answer please tell me if it was correct or not.
Answer:
<h3>
<u>
x = -7</u></h3>
Step-by-step explanation:
x-coordinate of both points is the same. That means the line is parallel to Y-axis
Equation of every line parallel to Y-axis is: x = x₀
where x₀ is the x-coordinate of any point from the line
x₀ = -7 so the equation is:
<u>x = -7</u>
