Answer:
y = 54
Step-by-step explanation:
We know the sum of the angles of a triangle are 180
72+y+y = 180
Combine like terms
72 + 2y = 180
Subtract 72 from each side
72-72 +2y = 180-72
2y = 108
Divide each side by 2
2y/2 = 108/2
y = 54

P= (2)(x-2)+(2)(5)
P= (x-2)+(x-2)+5+5
x²(x - 4)(2x + 5) = 0
x² = 0 or x - 4 = 0 or 2x + 5 = 0
√x = √0 or x = 4 or 2x = -5
x = 0 x = 
Answer: 0, 4,
