Answer:
Given that one of the angles of the given triangle is 60. Also given that the other two angles of the triangle are in the ratio 1: 2. Let one of the other two angles be x. Therefore, the second one will be 2x. We know that the sum of all the three angles of a triangle is equal to 180. 60 + x + 2x = 180 3x = 180 – 60 3x = 120 x = 120/3 x = 40 2x = 2 × 40 2x = 80 Hence, we can conclude that the required angles are 40 and 80.
