Honestly, I'm not the best with this part, but I think you got it right
A complimentary angle is when the angle is 90 degrees, but the only 90 degree angle ( L ) is not an option. What you put for the other ones makes sense to me too, so I would say just go to the next one
The answer is 2.7
hope this helps
Answer:
-20
Step-by-step explanation:
Y=3x-5
y-3x=-5
Times 2 from both side
y(2)-3x(2)=-5(2)
2y-6x=-10
Times negative from both side
(-)2y-6x(-)=(-)-10
-2y+6x=10
or
6x-2y=10
6x=2y+10
6x-2y=10
Furthermore, we see that both equation have the same 6x-2y=10 which means that both of them have infinity solutions, not a solution. Hope it help!
