Answer:
My exes lies, Jellyfish, my dry sense of humor.
Im just going out on a wing here but is one options 40 + 45
For the letter a it is x = 24
For the letter b it is x = 20
Just add 70 and 30 together and then subtract it from 180
70+30+x=180 100=180 subtract 100 from 180 and x=80 and to check this just add 70+30+80=180 it checks out
Hope this helps have a nice day
