The isosceles triangle has two sides congruent which mean they are equal. If two sides are equal, it also means that two angles are equal.
For triangle XYZ, we have angles shown below:
∠X + ∠Y + ∠Z = 180°
If ∠Y = a°, then we can have the expression for ∠X such as shown below:
∠X + a° + ∠Z =180°
∠X= 180° - a° - ∠Z
If ∠Z = ∠Y, then we have the final expression:
∠X = 180° -2a°
The value is 6 hundreths
it is in the hundreths place, so that would be your answer

Answer:
y = -2·x^2 - 5·x - 18
y = -2·(x^2 + 10·x + 36)
y = -2·(x^2 + 10·x + 36)
y = -2·(x - (-5 - √11·i))·(x - (-5 + √11·i))
Maybe there is a typo in the original question, because there is no factorisation in the real numbers.
Because the question is " find the minimum value of y" the coefficient before x^2 must be a positive number. so it could be
y = 2·x^2 - 5·x - 18
