Answer:
c
Step-by-step explanation:
100+75+70+x= 360° (sum of interior angles of quadrilateral)
x= 360-245= 115°
We are given

We can write it as

we can see that 2y is in first two terms
and -8 is in last two terms
so, we can factor it out

now, we can see that x+4 is common in both terms
so, we can factor it out

we can see that
x+4 is one of factor of terms
so, option-B..........Answer
22:6 is one of them. Do you need more than one?
