Your octagon has a central angle of 360 deg. Since you're speaking of an octagon, which implies that the octagon is made up of eight triangles, divide 360 deg by 8 to obtain the measure of each minor arc formed.
The general form and the standard form of the graph equation are 13x - 8y = 17 and 13x - 8y - 17 = 0 respectively
<h3>How to determine the equations?</h3>
From the graph, we have the following points
(x,y) = (5,6) and (-3,-7)
Start by calculating the slope:
This gives
Evaluate the differences
Evaluate the quotient
The equation is then calculated as:
This gives
Multiply through by 8
8y = 13(x - 5) + 48
Open the bracket
8y = 13x - 65 + 48
Evaluate the like terms
8y = 13x - 17
Subtract 13x from both sides
-13x + 8y = -17
Multiply through by -1
13x - 8y = 17 ---- this represents the standard form
Subtract 17 from both sides
13x - 8y - 17 = 0 --- this represents the general form
Hence, the general form and the standard form of the graph equation are 13x - 8y = 17 and 13x - 8y - 17 = 0 respectively

5)x= 67° and y= 32°
(x-15)°=52°(vertically opposite angles)
=>x= 52+15° = 67°
Similarly, 4y= 128°(vertically opposite angles)
=>y=128/4= 32°
6) x= 5° , y= 22°
12x+15=75°(vertically opposite angles)
12x=75-15°
12x=60°
x= 5°
6y-27°=105°
6y= 105+27°
6y= 132°
y= 22°
