AB=BC*AC
AB=SIN45*10
=0.707*10
AB=7.07

Its very to find out,
Sin 45 = opp/ hy
opp = sin 45 x hy
= 1/sq.root of 2 x 10
opp = 7.07

AB = ACsin45
AB = 10*0.707
AB = 7.07

Perpendicular AB
sin(45)= ---------------- = ------
hypotenuse 10

So,

AB = sin(45)x 10 = 0.707x10 = 7.07 Ans.

sin 45=AB/AC
1/2^2=AB/10
10* 1/1.4142=AB/10
10* 0.707=AB
7.07=AB
