AB = Side of larger triangle - Altitude of smaller triangle = 1 - Altitude of smaller triangle

We know the relation between the side and the altitude of an equilateral triangle: Altitude =

\frac{\sqrt{3}}{2}*SideAltitude of larger triangle =

\frac{\sqrt{3}}{2}*1 = Side of smaller triangle

Altitude of smaller triangle =

\frac{\sqrt{3}}{2}*\frac{\sqrt{3}}{2}*1 = \frac{3}{4}AB = 1 - 3/4 = 1/4 = 0.25

See the idea what I got is for 60degree = square root 3 times 30Degree & same way for 90 degree = 2 times 30 degree. i.e. 1:root3:2....

In this case i have understood root3/2 on a larger altitude. Now to find a side opposit to 60degree in smaller altitude, we have been given only 90degree side root3/2.. so how you calculated please tell.
