Answer:

40.5

Step-by-step explanation:

You are absolutely right. However, it is not that just because it "looks like half of it." This is due to the midsegment of a triangle theorem. This theorem states that when the sides are equal when divided by the segment, the segment is 1/2 the size of the base, which is 81. Therefore, x does equal 40.5. Hope this helped!
