1. Supplementary angle of 60
Solution:
Supplementary angles : Two angles are said to be supplementary angles, if the sum of their measures is `180^circ`
Supplementary of `60 ^circ` is the angle that when added to `60 ^circ` forms a straight angle (`180 ^circ`).
`=180 ^circ-60 ^circ`
`=120 ^circ`
2. Supplementary angle of 120
Solution:
Supplementary angles : Two angles are said to be supplementary angles, if the sum of their measures is `180^circ`
Supplementary of `120 ^circ` is the angle that when added to `120 ^circ` forms a straight angle (`180 ^circ`).
`=180 ^circ-120 ^circ`
`=60 ^circ`
3. Supplementary angle of 45
Solution:
Supplementary angles : Two angles are said to be supplementary angles, if the sum of their measures is `180^circ`
Supplementary of `45 ^circ` is the angle that when added to `45 ^circ` forms a straight angle (`180 ^circ`).
`=180 ^circ-45 ^circ`
`=135 ^circ`
4. is Supplementary angles 60, 120
Solution:
Supplementary angles : Two angles are said to be supplementary angles, if the sum of their measures is `180^circ`
`=60 ^circ + 120 ^circ`
`=180 ^circ`
Here sum is `180^circ`
So, `60 ^circ, 120 ^circ` are supplementary angles
5. is Supplementary angles 30, 60
Solution:
Supplementary angles : Two angles are said to be supplementary angles, if the sum of their measures is `180^circ`
`=30 ^circ + 60 ^circ`
`=90 ^circ`
Here sum is not `180^circ`
So, `30 ^circ, 60 ^circ` are not supplementary angles
