he wants 4 plants for each square meter of area.
therefore , for 84 m ² number of plants are
i.e 21 plants
hence , 21 plants are in the garden

140°
Supplementary angles sum to 180° , thus
angle = 180° - 40° = 140° ← other angle
A linear pair means that the sum of the angles is 180 degrees.
Therefore:
a + b = 180°
We know that:
a = b + 26°
b + 26 + b = 180
2b = 154
b = 77°
So,
a = b + 26 = 103<span>°</span>
