With long division the answer is 2411
N=30°. The sum of the angles is 180º. n+n+4n=6n, so 6n=180 and n=30°.
n=18°. 4n+n=90, so 5n=90, n=18°.
The angle of a a triangle is 180 so you do
180 - 44 = 136
136 - 31 = 105
so y = 105
9.18 equals 9 9/50 (proper fraction) or 459/50 (improper fraction)
I hope this is helpful!!
