Question

The angles of a triangle ar (3x)
(2x - 7) and (4x-11). Then value
of x is.​

Answer 1

Answer:

22

Step-by-step explanation:

sum of angles in a triangle=180

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

9x-18=180

9x=180+18

9x=198

x=198/9

x=22

Answer 2

Step-by-step explanation:

As we know that sum of interior angle of a triangle is. 180°

3x +(2x-7) +(4x-11)=180°

9x - 18 =180°

9x =180 + 18

9x =198

x =198/9

x =22° ANS.
