Answer:
I can use variables to represent the coordinates of the vertices for a general triangle, ∆ABC. Then I can calculate the midpoints of the sides in terms of those variables. Using the point-slope formula for the equation of a straight line, I can build the symbolic equations for the three medians, AE, BF, and CD. I can solve for the point of intersection for two of the medians, AE and BF, for example. Finally, I can prove the lines (i.e., medians) concurrent if the point I found also satisfies the equation of the line for CD.
I think the answer might be in the photo but we would need to see what we’re working with lol
The answer is C
you substitute 3200 in for y
3200 = 168x +8
3192 = 168x
x=19
I think the answer is 152 but I’m not 100% sure
