@Legos4ver16 @hardlyhuman I will be copying and pasting bits of information from this thread: https://questioncove.com/study#/updates/5a343684a9e9c8da8455980 "What type of triangle is this?" This question was intended to gauge how much you know about geometry, and was relevant to the question (as once you figure out that it is an isosceles triangle, you can use its characteristics to solve for x, and then the base). "It's actually @Legos4ver16 question, I told her I'd help her with it, but had no idea how." This is where the question took a down turn. In the future (this is for both of you) please ask questions yourselves. I really do not see the point of asking other users to do so. "Well, if they give us that two angles of a triangle are congruent, and the third angle is not, then we can determine that this is an isosceles triangle. Isosceles triangles have the characteristic of two base angles that are congruent to each other. They also have the characteristic of the sides opposite to the base angles being considered "legs." These legs are congruent to each other." Explained how you can identify that it is an isosceles triangle. Understand this, and know it. "What are the two sides opposite to our base angles (the angles that are congruent to each other) ?" The answer to this question is crucial in order to solve for x, and thus, the base of the triangle. I was looking for side AB and side CA. As I said above, those legs are congruent to each other. Since the expressions 8x - 4 and 5x + 11 represent the values of those sides, we can make them equal to each other. Then it is just a matter of solving x and inputting what you get into 4x - 2 and getting the value of the base. Let me know if you need help understanding this, or with the algebra @hardlyhuman
