**suchita**, Monday, May 5, 2014 at 2:47pmA-B = 10N

A=10+B-----Eq 1

given

50=root A2+B2 its square

now square on both aise..

25000=(10+B)+ B2

2500=100+B2+20B +B2

B2+ 10B-1200=0

B2-30B+40B-1200=0

B(B-30)+40(B-30)=0

(B+40)(B-30)=0

B=30 &

from eq 1

A =40

i hope soo u might be safistied with my answer.
