What is the value of s?

Given:

Given that a triangle with angles (s - 14)°, 2s° and (s - 18)°

We need to determine the value of s.

Value of s:

Let us use the triangle sum property to determine the value of s.

Thus, we have;

Simplifying, we have;

Adding the like terms, we get;

Thus, the value of s is 53.

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
