Since the sum of the angles of a triangle = 180°
Then (2x)º + (x + 60)º + (3x)º = 180°
(6x)° + 60° = 180°
(6x)° = 180° - 60°
x = 120° ÷ 6
∴ x = 20
Answer:
D
Step-by-step explanation:
-3(4x - 2) - 2x
-12x + 6 -2x
-14x + 6
You have to subtract the 3 officers who can not be chosen from all 35 members. So the probability is 1/32 because 35/3=32
