Answer: The given triangle is an obtuse triangle.
Step-by-step explanation: Let ABC be the given triangle, where the side lengths are as follows :
We are to check whether ΔABC is acute, obtuse or right.
We know that ΔABC will be
(i) Acute, if AB² + BC² > CA²,
(ii) Obtuse, if AB² + BC² < CA²,
(iii) Right, if AB² + BC² = CA².
Now, we have
So,
Therefore, the given triangle is an obtuse triangle.

Step-by-step explanation:
Hello, please consider the following.
When the parabola equation is like
The vertex is the point (h,k) and the focus is the point (h, k+1/(4a))
As the vertex is (3,-2) we can say that h = 3 and k = -2.
We need to find a.
The focus is (3,2) so we can say.
So an equation for the parabola is.
Hope this helps.
