There are one to two methods to solve this ques. I'll use the phaser method.
☆Phaser method:
》In this, first convert the superimposed wave in proper sine equation of wave.
》Then solve the waves in the form of vectors by putting them at axis.
☆Let's solve:
》
》Now, see the above image.
》phase difference between them is 90°.
》Resultant = (6²+8²)½
》amplitude = 10m
