An equilateral triangle is a triangle where all sides are of equal lengths. So, the angles are of equal values as well which is 60. We use the angle and the height of the triangle to determine the side length. We do as follows:
tan (60) = 15 / base/2
base = 10√3 = side length

Step-by-step explanation:
Parabola equation:
The equation of a parabola has the following format:
If 
, that is, x² is multiplied by a positive number, the function has a minimum value and the parabola opens up.
If 
, that is, x² is multiplied by a negative number, the function has a maximum value and the parabola opens down.
In this question:
From the graph, we already see that it opens down and has a max, and analitically, since 
, this is confirmed. The correct answer is given by option b.
