Answer 1

Answer:

60° , 60° , 60°

Step-by-step explanation:

Given,

Angles of the triangle are :-

3x° , 2x° + 20 , 5x° - 40

To Find :-

Angles.

Condition Required :-

Sum of the angles in a triangle is 180°

Solution :-

→ 3x° + 2x° + 20° + 5x° - 40° = 180°

5x° + 20° + 5x° - 40° = 180°

10x° - 20° = 180°

10x° = 200°

x° = 20°

The angles are :-

3x° = 3×20°

= 60°

2x° + 20° = 2(20°) + 20°

= 40° + 20°

= 60°

5x° - 40° = 5(20°) - 40°

= 100° - 40°

= 60°

3x, (2x + 20) , (5x - 40) = 60° , 60° , 60°
