Question

find the complementary and supplementary angle of 9°​

Answer 1

Step-by-step explanation:

Complementary angle:

Let the complementary angle be x

9+x=90

X=90-9

X=81

Supplementry Angle

Let the Supplementry Angle be x

9+x =180

X= 180- 9

X=171

Answer 2

Answer:

• Complementary angle of 9° = 81°
• Complementary angle of 9° = 171°

Step-by-step explanation:

Here, first let's understand the concept used.

Concept applied:

• Complementary angles are angles which sum up to 90°
• Supplementary angles are angles which sum up to 180°

Solution:

Finding the complementary angle of 9°.

x + 9° = 90°

→ x = 90° - 9°

→ x = 81°

Finding the supplementary angle of 9°

x + 9° = 180°

→ x = 180° - 9°

→ x = 171°
