Answer 2

First let's understand the concept.

→ Sum of all angles in any triangle is always 180°

→ This is known as Angle Sum Property.

Applying Angle Sum Property,

7x + 5x + 60° = 180°

⇒ 12x + 60° = 180°

⇒ 12x = 180° - 60°

⇒ 12x = 120°

⇒ x = 120 ÷ 12

∴ x = 10°

Know More:

If we need to find to find the angles,

7x = 7(10) = 70°

5x = 5(10) = 50°

Verification:

7x + 5x + 60° = 180°

→ 70° + 50° + 60° = 180°

→ 180° = 180°

LHS = RHS
