(i) We know that,

Sum of measures of supplementary angles is 180^o

It is given in the question that,

Angle = 105^o

Therefore,

Supplement = 180^o – 105^o

= 75^o

(ii) We know that,

Sum of measures of supplementary angles is 180^o

It is given in the question that,

Angle = 87^o

Therefore,

Supplement = 180^o – 87^o

= 93^o

(iii) We know that,

Sum of measures of supplementary angles is 180^o

It is given in the question that,

Angle = 154^o

Therefore,

Supplement = 180^o – 154^o

= 26^o
