Question

3. Identify which of the following pairs of angles are complementary and which are supplementary.
(i) 850, 95°
(ii) 25°, 65°
(iii) 9°, 8°
(v) 90°, 90°
(iv) 45°, 45°
(vi) 70°, 110°​

Answer 1

Answer:

Complementary Angles( Angles whose sum is 90°) ...(ii) 25° and 65°

(iv) 45°and 45°

Supplementary Angles( Angles whose sum is 180°) ...(v) 90° and 90°

(vi) 70° and 110°

Answer 2

Answer:

3.

i) Neither complementary nor supplementary angles

ii) Complementary angles

iii) Neither complementary nor supplementary angles

iv) Complementary angles

v) Supplementary angles

vi) Supplementary angles

Step by step explanation:

3.

i) 850° and 95° are neither complementary nor supplementary as they both do not add up to 90° ( complementary angle ) or 180° ( supplementary angle )

= 850°+95° = 945°

ii) 25° and 65° are complementary angles as they add up to 90°

= 25° + 65° = 90°

iii) 9° and 8° are neither complementary nor supplementary as both do not add up to 90° ( complementary angle ) or 180° ( supplementary angle )

= 9°+8° = 17°

iv) 45° and 45° are complementary angles as they add up to 90°

= 45°+45° = 90°

v) 90° and 90° are supplementary angles as they add up to 180°

= 90°+90°= 180°

vi) 70° and 110° are supplementary angles as they add up to 180°

= 70°+110° = 180°
