Answer:
80 is the measure because if aob is 40 then doe is 40 and dof is 120 minus the doe that 40 then you are going to get the mesuare which is 80
Answer:

Step-by-step explanation:
Coordinates are (0,6) and (1,3)
Slope = 
Slope = 
Slope = -3
<u><em>Now, Finding b</em></u>
Taking any Point
Point = (x,y) = (0,6)
So, x = 0, y = 6
<em>Putting in slope-intercept form to find b</em>

=> 6 = (-3)(0)+b
=> b = 6
<u><em>Now Putting slope and b in the formula to get the required slope-intercept form.</em></u>

=> 
Answer:
D
Step-by-step explanation:
12-(-3)=15
I think b is 106 I really hope this helps I’m sorry if it doesn’t
