Answer: x = 3 AI + MC = 21 Step-by-step explanation: For this problem, refer to the attached image. I tried to draw it based on the description of the triangle. A midsegement is a segment that connects two midpoints of a triangle. In this problem, AI is a midsegment. There are 2 theorems when it comes to the midsegment of a triangle. These are: 1. The midsegment is half the measure of the third side of the triangle. 2. The midsegment is parallel to the third side of the triangle. For this problem, we shall prove and use the 1st theorem. Similar triangles are triangles whose corresponding sides are proportional. Also, all of their corresponding angles are congruent. This means that all the sides share a common ratio. Like triangle congruence, there are theorems and postulates that prove triangle similarity. The symbol used for similarity is ~. We have two triangles in the figure, ΔMGC and ΔAGI. We are given that A is the midpoint of MG. This means that We also know, via segment addition that Substituting MA = AG to the equation gives us This means that MG is twice AG. Their ratio is 1:2. We can do the same thing for the other side of the triangle, GC. Since I is the midpoint, Via segment addition, Substituting again gives us. This means that GC is twice GI. Their ratio is 1:2. We now have 2 proportional sides. AG:MG = 1:2 = GI:GC. Observe ∠AGI and ∠MGC. They are the same angles, and therefore, congruent to each other. The SAS similarity states that: If two sides of a triangle are proportional to two sides of another triangle, and the angle between those 2 sides are congruent, then the two triangles are similar. We have 2 proportional sides (AGAG:MG = 1:2 = GI:GC) and the congruent included angle ( ∠AGI). So ΔMGC ~ ΔAGI. We return to back to what it means to be similar. All sides share a common ratio. The ratio of the sides of the triangles is 1:2. This means, the ratio of AI:MC is also 1:2. This is also known as the midsegment of a triangle theorem. We can now solve for x x is equal to 3.
