Question

plz solve it tommorow is my exam​

Answer 1

Answer:

We have

Sin x +sin y =1/4

Then, 2sin (x+y/2)cos( x-y/2)=1/4

And cos x +cos y =1/3

Now, 2cos(x+y/2).cos (x-y/2)=1/3

Now dived these equations

Then we get

Tan (x+y/2)=3/4.

Cos (x-y/2) will cancel.

And we get our answer

Hope it helps u in your exam
