Answer 1

HEY MATE ✌✌✌✌✌✌✌✌



HERE IS YOUR ANSWER :-

Angle between A vector and B vector = 110° - 20°


= 90°
in this case,

we use vector formula

R^2 = a^2 + b^2 +2abcos¢
= (3)^2 + (4)^2 + 2 * 3 * 4* cos 90°
= 9 + 16 + 24 * 0 we know that (cos90° = 0)
= 25 +0
= 25
after that,

R = √25
= 5m

Answer:

You Need Sympathy is feeling bad for someone else because of something that has happened to them. We often talk about it and feel sympathetic when someone has died, or something bad has happened, saying 'Give them my sympathy', or 'I really feel for them'.
