Answer:
Step-by-step explanation:
sum of angles of a triangle= 180°
x+2x+2x+10=180
5x+10=180
5x=170
x=170/5
x=34
.:
x=34°
2x=34×2=68°
2x+10=2×34+10=68+10=78°
Answer: The equation has a positive y-intercept
This is because the constant is +10
X,y
1092, 109
671, 67
985, 99
The rate is 10.02 and I found that by dividing x with y
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis.
According to the data of the statement we have the following points:

We found the slope:

Thus, the equation is of the form:

We substitute one of the points and find b:

Finally, the equation is:
