Answer:
5/8
Step-by-step explanation:
-5 from 5 and put it on the other side
-8y=-5+40
then divide -5 by -8 then you get 5/8
parrelel then means the same slope due to the fact they never touch.
K. A quadrilateral has a total angle measure of 360. We know that two of the angles are 90, so we can subtract 180 from that. We’re left with 180. So we can make it into and equation. X+2x=180. Simplify and solve, and you get that x=60.
L. Again, a quadrilateral has a total of 360. So we can subtract the right angle from that and get 270. Put it into and equation, and you get x+2x+3x=270. Simplify and solve, and you get that x=45.
