Question

The height of an equilateral triangle is 46 inches.

What is the approximate length s of the triangle's side?


Please explain your answer

Answer 1

All angles in an equilateral triangle are 60°, so you can use trigonometry and say that
sin(60) = 46/side
side = 46/sin(60)
side = 46/0.866 = 53.12. I hope this helps!
