Answer:

mAOB = 139 degrees

Step-by-step explanation:

1) By supplementary angles, you can set up the equation:

mAOB + mBOC = mAOC = 180

8x + 51 + (6x - 25) = 180

2) Solve for x:

14x + 26 = 180

14x = 154

x = 11

3) Substitute x into 8x + 51 to get mAOB:

8(11) + 51

=88 + 51

=139

Find the slope of the line that passes through (-1,6) and (15,6)

svp [43]

Slope = $\frac{Y2 - Y1}{X2 - X1}$
------------------------
6 - 6 = 0
15 - (-1) = 16
0 / 16 = 0
--------------------------------
You have a slope of 0, meaning that this is a straight horizontal line
