Answer 2

Answer:

1st angle → 30°

2nd angle → 60°

3rd angle → 90°

Step-by-step explanation:

Let the angles in the ratio 1 : 2 : 3 be x, 2x and 3x

Sum of interior angles of a triangle is 180°

According to the question,

x + 2x + 3x = 180

→ 6x = 180

→ x = $\dfrac{180}{30}$

→ x = 30

∴ 1st angle → x

→ 30°

∴ 2nd angle → 2x

→ 2 * 30

→ 60°

3rd angle → 3x

→ 3 * 30

→ 90°
