Find the magnitude of the sum of a 10m displacement and a 5 -m displacement when the angle between them is 45
Answers: 3
![R^2 = a^2 + b^2 -2ab \times cos(\theta)\\\\R^2 = 10^2 + 5^2 - [2\times 10 \times 5 \times cos(45)]\\\\R^2 = 125 - [100 \times 0.7071]\\\\R^2 = 125 -70.71\\\\R^2 = 54.29 \\\\R= \sqrt{54.29} \\\\R = 7.37 \ m](/tpl/images/1177/3699/d5612.png)
