Answer:
y=2
Step-by-step explanation:
1/3 (y+7) = 3(y-1)
Multiply each side by 3 to get rid of the fraction
3*1/3 (y+7) = 3*3(y-1)
y+7 = 9(y-1)
Distribute
y+7 = 9y - 9
Subtract y from each side
y+7-y = 9y-y-9
7 = 8y -9
Add 9 to each side
7+9 = 8y-9+9
16 = 8y
Divide each side by8
16/8 = 8y/8
2 = y
X=y=29 divided by square root of 2.
Hope this helped!!!
Sorry I could not give you the exact value.
I guess it is 20.506
11n+33 is the correct answer
It could be 10 which would make the triangle a right triangle, since the values follow the Pythagorean theorem (a^2+b^2=c^2)
