12) The altitude an equilateral triangle is 21 cm, find the lengths of the sides of the triangle. Leave your answer in simplest radical form.
I first discovered that the
area of the equilateral triangle is
. I then considered a point in the center of a triangle, and then
connected it to each of the vertices. From there I gathered that
each of the 3 triangles formed by these line segments gave an area
of
. Please use the pigeonhole principle to explain.
Consider an equilateral triangle of side equal to 1. Choose 7 points inside the triangle, arbitrarly. Show that three of them...
3) Three long wires (2 m long) are arranged in an equilateral triangle with a side length of 10 cm. The view is edge on (two wires coming out of the paper, one going in). Find: a) the net magnetic field vector at the center of the triangle, and b) the net force vector at point P (the midpoint of a side). 10 A
