Question

what is the difference between complementary and supplementary angle of 75?

Answer 1

complementary angle means the sum of two adjacent angles is equal to 90°.So complementary angle of 75° is equal to (90°-75°)=15°
supplementary angles are the two adjacent angles whose sum is equal to 180°. So supplement of 75°is
(180°-75°)=105°

Answer 2

COMPLIMENTARY ANGLE:
If the Sum of 2 adjacent angles are 90° then 2 angles are said to be complementary.

Complimentary angle of 75°= 90°- 75°= 15°

SUPPLEMENTARY ANGLES
If the Sum of 2 adjacent angles are 180° then 2 angles are said to be supplementary

Supplementary angle of 75°= 180°- 75°=105°
