Question

The three angles of a triangle are 11x-1,4x+15 and 20x-9.find the measure of all the angles of the triangle.with formula plz

Answer 1

Answer :
           We know that ,
   Sum of Angles of a Triangle = 180
therefore ,
       (11x-1) +(4x+15)+(20x-9)=180
     or 11x-1+4x+15+20x-9  = 180
     or 11x+4x+20x -1+15-9 =180
      or 35x +5 =180
      or 35x = 180 -5
     or 35x =175
     or x =175/35
     or x =5
Therefore the angles of triangle are 
               11x -1 =11*5 -1 = 55 -1 = 54 
               4x+15 =4*5+15 =20+15 =35
               20x-9  =20*5 - 9 =100 -9 =91
Therefore three angles of a triangle are 54,35 and 91.
Hope this helps you.
