How to find angle of inclination of an equilateral

  1. Oct 6, 2013 #1
    1. The problem statement, all variables and given/known data
    How do i find the angle of the incline of an equilateral ramp with equal sides of 50m and with a horizontal component force of 50 N on a mass of 1kg.


    2. Relevant equations




    3. The attempt at a solution

    Even though i think of 'equal lateral triangle. wouldn't it be 60*?

    But if not i would think that i can get the angle by taking the inverse sine right?

    really confused....

    Of course it's 60 degrees. The sum of the angles of any triangle is 180 degrees. An equilateral triangle has three equal angles. Yes? So any one angle must be 60 degrees, yes?

    That is what i thought, but i have no idea why someone else was telling me that i needed to find some other measure
