Answer:

Explanation:
First displacement of the particle is given as
= 11 m at 82 degree with positive X axis
so we can say


resultant displacement of the particle after second displacement is given as
r = 8.7 m at 135 degree with positive X axis
so we can say


now we know that

now we have

so we will have


so angle of the second displacement is given as
