Question

please help me in this question​

Answer 1

Step-by-step explanation:

Let the angles be 2x, 3x and 4x

We know that the sum of angles of a triangle is 180°

2x+3x+4x=180°

9x=180°

x=20°

The angles are:-

2x=40°

3x=60°

4x=80°

Answer 2

Let the measure of the first Angle be 2x

Let the measure of the 2nd Angle be 3x

Let the measure of the first Angle be 4x

Then, ACCORDING TO ANGLE SUM PROPERTY OF A TRIANGLE, we have -

2x° + 3x° + 4x° = 180°

9x° = 180°

x = 180° ÷ 9°

x = 20 °

ANSWER - measure of the first Angle = 2X = 40°

measure of the 2ND Angle = 3X = 60°

measure of the 3rd Angle = 4X = 80°
