Question

What is the length of the side of an equilateral triangle inscribed in a circle at radius 5?

Answer 1

it would have to be 5

Answer 2

@jonnymiller The answer here is 5 sqrt 3 ...

Answer 3

duh sorry lapse in judgement...its easrly

Answer 4

k yeah....you have to set it up with trig...so break the equallateral triangle up in to a right triangle with one side equal to the radius. then use the tangent function to solve

Answer 5

knowing that the angles in a equallateral triangle are 60 or pi/3 rad

Answer 6

then you get tan(60)=x/5
then solve for x
