Could someone please help me ASAP? I need a full explanation. P. S I will name u brainliest!! Thanks!

y = 90 degrees.

Step-by-step explanation: We are given that the supplementary angle of angle y is equal to 90 degrees. By definition, that means that y is also equal to 90 degrees. The solution would be:

y + 50 degrees + 40 degrees = 180 degrees

y + 90 degrees = 180 degrees

y = 180 degrees - 90 degrees

y = 90 degrees

hope this helps! :)

answer: 1 + 1 = 11

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
