"A hiker starts at point P and walks 2.0 kilometers due east and then 1.4 kilometers due north. The vectors in the diagram below represent these two displacements.
Using a metric ruler, determine the scale used in the vector diagram"
Here, you need to use your "Protractor" as it is given in the question, but we can calculate the value with the help of our mathematical calculation too: [ Protractor can be use only in real life, not here ]
Draw an imaginary line from initial position to final position. Now, In that triangle, tan x = P/B tan x = 1.4 / 2 tan x = 0.70 x = tan⁻¹ (0.70) x = 35 [ tan 35 = 0.70 ]
