If they are perpendicular then...
A+B = (A2 + B2)^1/2
= (4+100)^1/2
= 10.20
A+B + C = 15
A+B = (A2 + B2)^1/2
= (4+100)^1/2
= 10.20
A+B + C = 15

The concept of vectors must be used ..
And thanks
How A+B+ C=15 ??
Can u explain
Just like A+B....
Means B+C ?
A+B is vector now then just like we added A+B we will add (A+B) and C...
hmm okk
