(i) 117°

Supplement of angle = 180° – θ

Supplement of 58° = 180° - 63°

= 117°

(ii) 42°

Supplement of angle = 180° – θ

Supplement of 58° = 180° - 138°

= 42°

(iii) 126°

Right angle = 90°

of a right angle = × 90°

= 54°

Supplement of 54° = 180° - 54°

= 126°

(iv) 104°24’

Supplement of angle = 180° – θ

Supplement of 75°36’ = 180° - 75°36’

= 179°60’ - 75°36’

= 104°24’
