The line tangent to the graph of the twice-differentiable function f at the point x=5 is used to approximate the value of f(5.25). Which of the following statements guarantees that the tangent line approximation at x=5.25 is an overestimate of f(5.25) ?

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
