Answer 3

ok well its a supplementary angle which will equal 180 so add them both , set them equal to 180 and solve for y

Answer 4

so its d right? @wendylisette

Answer 5

hold up im tryna work it out

Answer 6

ok thanks

Answer 7

ugh help me out i havent done geometry ina while

Answer 8

me neither lol i need helppppp

Answer 9

lol ok but theyre supplementary for sure because when added they'll be 180 , we got that lol

Answer 10

yeah i know that part lol

Answer 11

why did you guess d ? lol

Answer 12

i hope you know i have my whole class tryna figure this issh out for you haha

Answer 13

ok i got it , set 3x = 90 and solve for x . it will give you x = 30 . then go on to the next side and plug in 3o for x and set the equation equal to 90 because that side is 90 as well 2 ( 30 ) + 3 y = 90 and solve you should get y = 10 .

Answer 14

to check if its right plug the numbers in the variable , and add both equations , it should give you 180
