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

Assoli18 [71]

Answer:

91 animals

Step-by-step explanation:

Because every elephant saw 3 monkeys, there were 9 * 3 = 27 monkeys and because every monkey had 1 tortoise in each hand and we know that monkeys have 2 hands, there were 27 * 2 = 54 tortoises. To find the total number of animals that were going to the river, we can calculate 1 + 9 + 27 + 54 = 91 animals.
