Answer:
1/4
Step-by-step explanation:
The slope can be found using the slope formula with the two left-most marked points:
m = (y2 -y1)/(x2 -x1)
m = (6 -5)/(0 -(-4)) = 1/4
The slope of the line is 1/4.
Answer:
30.25
Step-by-step explanation:
All angles of a line must add up to 180. Since we already know that one angle is 90 degrees, we know that the other angles should add up to 90 degrees in order for all of the angles to add up to 180 degrees:
(3x-7)+(x+8)=90
4x+1=90
4x=89
x=22.25
22.25+8= 30.25
