heya friends !!
it's easy.....
by using distance formulae...
let one coordinate be A(10cos30,0) and B(0,10cos60)
=>√(0-10cos30)^2+(10cos60-0)^2
=>100cos^2 30°+100cos^2 60°
=)100*[√3/2]^2+100(1/2)^2
=>25*3+25
=>100 ans....
hope it help you..

The answer is✓(0-10 cos30)^2+(10 cos60-0)^2
✓100cos^230+100 cos^60
✓100{✓3/2}^2+{1/2}^2
✓100(3/4+1/4)
✓100×1
✓100=10 units....is the answer ..........very easy
✓100cos^230+100 cos^60
