Well according to my calculations the image isn't exactly correct, but:
n(unknownangle) = 180 - 125 = 55
360 = 120 + 55 + 90 + x
x = 95
180 - 95 = 85
------------------
x = 95
y = 85
We can do this by factoring: x^2 + 5x - 36, which is (x+9)(x-4)
We plug f(x) as 0, so (x+9)(x-4)=0, so x = -9 and x = 4
The x-intercepts are (-9, 0) and (4, 0).

Hope this helps!
Answer:
one solution
Step-by-step explanation:
x + y = 6 so 2x + 2y = 12
That means 3y = 9 so there is only one solution. x also equals 3
I can’t see the whole problem but The triangle is SAS and it it is translated
