Given that the angles of the triangle are in ratio 1 : 2 : 3
Let, the angles be a, 2a, 3a
Therefore, we know that
Sum of all angles if triangle is 180°
a + 2a + 3a = 180°
6a = 180°
a = \(\frac{180}{6}\)
a = 30°
Since,
a = 30°
2a = 2 (30°) = 60°
3a = 3 (30°) = 90°
Therefore, angles are a = 30°, 2a = 60° and 3a = 90°
Hence, angles are 30°, 60° and 90°.
