Answer: Length of MC is 16 milimeters
Step-by-step explanation:
Since we have given that
There is an equilateral triangle which has a perimeter of 96 milimeters.
As we know the formula for "Perimeter of equilateral triangle "
Since a perpendicular bisector is drawn from angle A to side BC at point M.
As we know that perpendicular bisector divide the line segment into two equal parts .
So, Length of MC will be
Hence, Length of MC is 16 milimeters.

Answer:
the coordinates of the center of rotation is (4 , 3)
Step-by-step explanation:
*The line which passes through points (4 , 1) and (4 , 5) is vertical because the points have same x coordinates and its length is 5 - 1 = 4
*The line which passes through points (2 , 3) and (6 , 3) is horizontal because the points have same y coordinates and its length is 6 - 2 = 4
*These two lines intersect each other at their mid-point and this mid-point is the center of rotation
*The mid point is
