Answer:
Step-by-step explanation:
The two dots on the bottom of this figure define the base of a triangle. If we now use a compass to draw the blue arcs on either side, as shown, the arcs will intersect at two points. A straight line drawn through these two points will be perpendicular to the base. The triangle will be isosceles and could be (but doesn't have to be) equilateral.
Answer:
The third option is correct: 5.7 units, M(7, 5, 2.5).
Step-by-step explanation:
The distance is √ [(9-5)^2 + (7-3)^2 + (3-2)^2 ]
= √ (16 + 16 + 1)
= √33
= 5.7.
The mid point = (9+5)/2 , (7+3)/2, (3+2)/2
= (7, 5, 2.5).
