I've answered this before, but only partially. I'm not sure about the second part, but I think the first one is 10
First we need to understand that the sum of adjacent angles on a straight line is 180°,meaning that when all the angles are added up the answer would be 180°
Here's how we can set up the equation:
2x+100°=180°
2x=80°
x=40°
Thus the answer is 40°
Again,hope it helps!
Answer: Y intercept: 5 The slope of the line is: 2
Step-by-step explanation:
Y=mx+b is y-intercept form
So you have to solve this equation for y.
This looks like:
-2x+y=5
+2x +2x
y=2x+5
