Answer: The length of BC is 22 units.
Explanation:
It is given that the Triangle ABC with horizontal side BC. Vertex A lies above side BC. Angle B and angle C are marked congruent. The length of side AC is labeled as 2x-24. The length of side AB is labeled as x-2. The length of side B C is labeled as x.
If two angles of a triangle are same it means the triangle is an isosceles triangle.
Since the angle B and C are congruent therefore the lines AB and AC are same.



Since the side BC=x therefore the measure of BC is 22 units.
Answer:

Step-by-step explanation:
we are given an algebraic function in x, such that

To find when second derivative >0
For this let us find first and second derivative by successive differentiation.

when ii derivative >0 we have
60x^3-30>0
