An obtuse triangle must have an angle greater than 90degrees (cannot equal 90). Therefore, A. would be the correct answer. This is because A. is the only set of angles that includes an angle greater than 90. Also, all angle measures add up to equal 180degrees.
You mean 5 points
the answer is 6.
Answer:
See below.
Step-by-step explanation:
The given equation is in vertex form. We can convert it to standard form as follows:
y = a(x - h)^2 + k
y = a(x^2 - 2hx + h^2) + k
y = ax^2 - 2ahx + (ah^2 + k) (answer).
