Aboat travels 30 miles north, 20 miles east and 40 miles northeast. what is the angle of rotation of the boats direction from start to finish

The angle of rotation of the boats direction from start to finish = 50.36⁰ to east towards north.

Step-by-step explanation:

Let x axis be east direction and x axis be north direction.

The boat first travels 30 miles north

⇒ Displacement = 30 j

Then boat travels 20 miles east

⇒ Displacement = 20 i

And at last the boat travels 40 miles north east

⇒ Displacement = 40·cos 45 i + 40·sin 45 j

                            = 28.28 i + 28.28 j

Total displacement = 48.28 i + 58.28 j

⇒ θ = 50.36⁰

Hence, The angle of rotation of the boats direction from start to finish = 50.36⁰ to east towards north.

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300
