To complete the sentence using deductive reasoning, we need to apply what we know about the properties of triangles and angles.
Given: Delta ABC with AB = AC
We are also given that < B = 40 degrees.
Since AB = AC, the triangle is isosceles. In an isosceles triangle, the angles opposite the equal sides are also equal.
Therefore, we can deduce that < C is also 40 degrees (because it is opposite the equal side AC).
So, completing the sentence using deductive reasoning:
If < B = 40 degrees, then < C = 40 degrees.
Therefore, the correct answer is option e) 40.
