Question

If fraction numerator b over denominator c plus a end fraction plus fraction numerator c over denominator a plus b end fraction equals 1 then

  1. A equals 60 to the power of ring operator
  2. B equals 60 to the power of ring operator
  3. C equals 60 to the power of ring operator
  4. A equals 90 to the power of ring operator

hintHint:

The angles of the triangle ABC are denoted by A, B, C and the corresponding opposite sides by a, b, c. solve If fraction numerator b over denominator c plus a end fraction plus fraction numerator c over denominator a plus b end fraction equals 1 then angle.

The correct answer is: A equals 60 to the power of ring operator


    If fraction numerator b over denominator c plus a end fraction plus fraction numerator c over denominator a plus b end fraction equals 1 then
    fraction numerator b over denominator c plus a end fraction plus fraction numerator c over denominator b plus a end fraction equals 1
b squared space plus space a squared space plus space c squared space plus a squared space equals space c b space plus space c a plus space a b space plus space a squared
b squared space plus space a squared space plus space c squared space space equals space c b space plus space c a plus space a b
i t space m e a n s space a space equals space b space equals space c space s o space e v e r y space a n g l e space o f space t r i n g l e space i s space 60 degree.
     
     
     
     

    All three sides are equal. All three angles are congruent and are equal to 60 degrees. It is a regular polygon with three sides. The perpendicular drawn from vertex of the equilateral triangle to the opposite side bisects it into equal halves.
