sin45=AB/10
.707=AB/10
AB=7.07

Sin45 value = 1/1.414 = 0.707213579

hyp^2=opp^2+adj^2

10^2=x^+x^2(opp=adj=x,isosceles triangle)

height(h)=x=7.07

Sin 45 = AB/AC
so, AB = AC x Sin45
AB = 10 x Sin 45
AB = 7.07

From the given diagram, let AB=BC=x and AC=d
x^2 + x^2 = d^2
2(x^2) =d^2
on Substituting the value of d=10
2(x^2) = 100
x^2 = 50
= 2x25
x = 5 x [(2)^(1/2)]
= 5 x 1.141
= 7.07

sin45 = 0.70
0.70*10 = 7.07

Let base and height= x (becoz angle is 45)

So x2+X2= 2X2=100

HENCE X=7.07

Sin45=ab/ac
where ac=10
then ab=sin45*ac
ab=.707*10
ab=7.07

Sin 45 = AB/AC =AB/10
AB = .0707X10 = 7.07
AB=7.07
