Hello there!
Sense this is a 360 degree angle, it is divide by 2. This would then be considered 180. If you (noticed) on the other side, it shows us that . . .

We then do (180-19)

Answer:
Neither of them are right
Step-by-step explanation:
First, let's actually solve this equation:
8 ( x - 5 ) = 8x + 40
Distribute on the left:
8 ( x - 5 )
( 8 x X ) + ( 8 x ( -5 ) )
8x - 40
8x - 40 = 8x + 40
Add 40 to each side:
8x = 8x + 80
Subtract 8x from both sides:
0 = 80 
0 ≠ 80
There are no solutions to the equation
