  2. Use sine rule in the triangle to get sin(3α)=2sin(α) which gives α=30 deg. or 4x^2 = x^2+(x+1)^2 with x=(1+√3)/2 as the only admissible root.

  3. draw a line from top to the base which divide the angqle at the top:2a and a.so there exist a equilaterel triangle with side x.2a=60 and a=30.In the 90-60-30 triangle x=1+√3)/2
