Question

see like this..... so can u explain it to me

Answer 1

brother first u should prove similarity between those triangles then by cpst u arrive cd/bc=ac/ab=p/a=b/c

p/a=b/c
p=ab/c

1/p=c/ab(making inversonaly propotion)
1/p^2=c^2/a^2b^2 (squaring )
1/p^2=a^2+b^2/ab^2
1/p^2=a^2/ab^2+b^2/ab^2
1/p^2=1/b^2+1/a^2 (cancelling) a ND b
