Answer 1

Answer:

144 is answer because angle 1 is 72 then angle 2 is the double of 72

Answer 2

Answer:

angle 2 is 108°

Step-by-step explanation:

a||b and there is a transversal on them

i). angle 1 = angle 3 (corresponding angles )

72° = angle 3

ii) angle 2+ angle 3 = 180° ( linear pair)

angle 2 +72. =180°

angle 2. = 180-72 = 108°
