4. is Complementary angles 60, 30

Solution:


`=60 ^circ + 30 ^circ`

`=90 ^circ`

Here sum is `90^circ`

So, `60 ^circ, 30 ^circ` are complementary angles

5. is Complementary angles 60, 50

Solution:


`=60 ^circ + 50 ^circ`

`=110 ^circ`

Here sum is not `90^circ`

So, `60 ^circ, 50 ^circ` are not complementary angles
