Answers
Given : pair of angles a. 90°, 90° b. 32°, 58° (c) 0°, 180° d. 76°, 104°
To Find : Which of the following pairs of angles is not a pair of supplementary angles
Solution:
Two angles are called supplementary when their measures add up to 180 degrees.
a) 90°, 90°
=> 90° + 90° = 180°
pair of supplementary angles
b) 32°, 58°
=> 32°+ 58° = 90°
90° ≠ 180°
Hence not a pair of supplementary angles
(c) 0°, 180°
=> 0° + 180° = 180°
pair of supplementary angles
d) 76°, 104°
=> 76° + 104° = 180°
pair of supplementary angles
Hence b. 32°, 58° is not a pair of supplementary angles.
Phloem tissue consists of conducting cells, generally called sieve elements, parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells and supportive cells, such as fibres and sclereids.
