Step-by-step explanation:
1x+2x+60 = 180degree (ASP)
3x+60=180 degree
3x = 180-60
3x = 120
x = 120 / 3
x (<1) = 40 degree
therefore 2x (<2) = 40*2 = 80 degree

Step-by-step explanation:
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°.
