Question

3 angles of a triangle are (x+20), (x+40) and x degrees find the angles​

Answer 1

Step-by-step explanation:

We know that,

Sum of all angles of a triangle is 180°

According to the question,

⟹ (x + 20)° + (x + 40)° + x = 180°

⟹ 3x + 60° = 180°

⟹ 3x = 180° - 60°

⟹ 3x = 120°

⟹ x = 120/3

⟹ x = 40° ans.

And other angles are :

(x + 20)° = 60°

(x + 40)° = 80°

Answer 2

Step-by-step explanation:

We know that,

Sum of all angles of a triangle is 180°

According to the question,

⟹ (x + 20)° + (x + 40)° + x = 180°

⟹ 3x + 60° = 180°

⟹ 3x = 180° - 60°

⟹ 3x = 120°

⟹ x = 120/3

⟹ x = 40° ans.

And other angles are :

(x + 20)° = 60°

(x + 40)° = 80°

HOPE THIS IS HELPFUL !!
