Answer 1

Hey buddy
Here we go

We know sin-¹ x= pie/2 -cos-¹x
So, Putting this in first equation we get...

pie-2cosx-¹-3cos-¹x=4

so, pie -4=5cos-¹x

So, cos-¹x=pie-4/5

Putting it in equation 2 we get

pie-2cis-¹x+3cos-¹x=pie +cos-¹x=pie+pie-4/5

So, answer is 2pie -4/5=10pie-4/5

Hope it's helpful for you dear friend
