Write the supplement of each of the following angles :

(i) 58°

(ii) 105°

(iii) 0.6 of a right angle

(iv) (x - 30)°

(v) 62° 56'

(vi) 83° 45' 30"

If x° and (x + 30)° are complements of each other, find the value of x.

Two complementary angles are in the ratio 4 : 5. Find the angles.

Two supplementary angles are in the ratio 7 : 8. Find the angles.
