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.

Answer:
yes
Step-by-step explanation:
Given
57 < 11x ← substitute x = 8
57 ← 88 ← True
Thus x = 8 is a solution to the inequality
Answer:
All of the angles are 60!
Step-by-step explanation:
the sum of all angles will be 180. the angles are conguent....180-60=120
120/2=60
