Question

The angles of a triangle are (3x)°, (2x – 7)° and (4x – 11)°, than the value of x
​

Answer 1

Answer:

22

Step-by-step explanation:

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

Hence, (3x)°+ (2x – 7)° + (4x-11)°=180°

3x+2x-7+4x-11=180

9x-18=180

9x=198

x=22

Answer 2

Answer:

according to the questions,

angles of a triangle = (3x°), (2x-7)°, (4x-11)°

(3x°)+ (2x-7)° + (4x-11)° = 180°. [angle sum property]

3x° + 2x°-7° + 4x°-11° = 180°

9x - 18° = 180°

9x = 180° + 18°

x = 198/9

x = 22°
