Answer:
24°, 16° and 140°.
Step-by-step explanation:
Let the angles, in ratio, are 3a and 2a.
In question, sum of 3a and 2a is (7/2) of third angle.
Third angle = (7/2){3a + 2a} = (7/2)(5a)
= > third angle = 17.5 a
In triangle, sum of all angles = 180°
= > 3a + 2a + 17.5a = 180°
= > 22.5a = 180°
= > a = 180°/22.5
= > a = 8°
Therefore angles are:
3a = 3(8°) = 24°
2a = 2(8°) = 16°
17.5a = 17.5(8°) = 140°
Angles are 24°, 16° and 140°.
