What is complimentary angle ???

Complimentary angles are those angles which together makes a 90° or whose sum is 90° which is a right angle.

Now ,2/3 of 90

$= > \frac{2}{3} \times 90 = 30 \times 2 = 60$

Here,first angle is 60°

=>Second complimentary angle =x+60=90(sum of complimentary angle is 90)

=>x=90-60

=>x=30°

complimentary angles are :$\bold{\red{30°\: and\: 60°}}$

Check:

=>30+60=90°[proved]

Supplementary angles

Supplementary angles are those angles whose sum together makes 180°

e.g=>30+150=180°

=>60°+120°=180°

=>100+80=180°
