You walk 48 m to the north, then turn 60° to your right and walk another 45 m. how far are you from where you originally started?

Sin θ = opposite / hypotenuse

Sin(30) = opposite / 48m

Sin (30) * 48m = opposite

24m = opposite

Sin(30) = opposite / 45 m

Sin(30) * 45 m = opposite

22.5 m = opposite

24m + 22.5m = 46.5 m

I am 46.5m away from my original starting point.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
