Does anybody know the answer?

Taking a lucky guess but if you look at 120 it kind of looks like the same angle inside the triangle so I think that it is 120

y+25=120

y = 120-25

so y= 95

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
