To set this up you will set the two angles equal to 180° since it is a straight line
This will make the equation x+6x+19=180
Combine like terms. 7x+19=180.
Subtract 19 from both sides. This will make it 7x=161
Divide both sides by 7. That will make it x=23
Next plug in the x to solve for abc. 7(23)+19. This equals 157

X= 23

Hope this helped :)

Let's simplify ~

$\qquad \sf \dashrightarrow \:( - 2 - 5i) - ( - 4 + 6i)$

$\qquad \sf \dashrightarrow \: - 2 - 5i + 4 - 6i)$

$\qquad \sf \dashrightarrow \: - 2 + 4 - 5i- 6i)$

$\qquad \sf \dashrightarrow \:2 - 11i$
