Answer:
Given,
one angle of a triangle is 60°.
Let the other two angles be x and 2x.
We know that, the sum of all angles in a triangle is equal to 180°
x + 2x + 60° = 180°
3x = 180° - 60°
3x = 120°
x = 40°
So, the other two angles will be x = 40° and 2x = 2 x 40° = 80°

Step-by-step explanation:
1 ½ = 3/2 x
1 ⅓ = 4/3 x
60° + 3x/2 + 4x/3 = 180°
3x/2 + 4x/3 = 120°
{ 3×(3x) + 2×(4x) } / 6 = 120°
{9x + 8x} / 6 = 120°
17x / 6 = 120°
17x = 120×6
17x = 720
x = 720/17
x = 42.35 (approx)
so... the angles are....
3x/2 = 63.525(approx)
4x/3 = 56.466(approx)
