Question

A man goes 30m north then 40m east then find displacement​

Answer 1

By using Pythagorus Theorem,

${30}^{2} + {40}^{2} = {h}^{2} \\ 900 + 1600 = {h}^{2} \\ 2500 = {h}^{2} \\ \implies \boxed{h = 50cm}$

Answer 2

Answer:

50cm displacement

Explanation:

AC²=AB²+AC²

AC²=30²=40²

AC²=900+1600

AC=√2500

AC=50CM
