Question

1) If A+B=Ř and 2Ā+Ēis perpendicular to B then
1)A-R
2)B = 2R
3)B = R
4)B = A​

Answer 1

Answer:

0

Explanation:

because :

here given that a+b=r

and (a+2b)is perpendicular to: a

so:(a+2b)multiplied by 9=0

a square+ 2ab=0

a square =2ab

put value of a form (a+b=r)=(a=r-b)

r-b=2b

r=2b+b

r=-b

r+b=0 :it it reqired a relation
