In vectors, magnitude of a vector represents displacement of an object or person, be in any unit, in a Cartesian plane. For example,
= ai + bj
dr = gi + hj B
hj
di
gt
al
e total displacement of these is given b
||as + dall = A unit

Badrul is currently camping in a jungle. He left his camp site three days ago to continue his adventure. On the first day he went 5 miles to the east and 7 miles to the north. On his second day, he moved 8 miles to the east and 4 miles north. Finally, on the third day, he ventured 3 miles east and 8 miles north. Assume his camp site coordinate is (0,0). Find
(a) Badrul location in coordinate after three days of adventure
(b) the total displacement Badrul made from the camp site after three days of adventure.
(c) the angle relative to the eastern direction, from the camp site to Badrul's final location. Round your answer to the nearest degree.
