Answer:

[tex]y + 44 = 180 (sum \: of \: straight \\ \: angel \: is \: 180)\\ \\ y = 180 - 44 \\ y = 136 \\ the \: sum \: of \: triangle \: are \: 180 \\ \\ y - 43 + y + 136 = 180 \\ 2y - 93 = 180 \\ 2y = 180 - 93 \\ 2y = 87 \\ y = \frac{87}{2} \\ y = 43.5[/tex]

Answer:

y=87°

Step-by-step explanation:

y+44°=y+y-43°

or,44°+43°=2y-y

or,87°=y

So,y=87°
