Question

the angles of triangle are 3x°(2 x -7 °) and 4 x-11°​

Answer 1

Step-by-step explanation:

the angles of triangle are 3x°, (2 x -7 °) and (4 x-11)

so, the sum of angles of triangle = 180°

3x° + (2 x -7 °) + (4 x-11)° = 180°

9x - 18 = 180°

9x = 198°

x = 22°

so , angles of the triangle are 3x = 66° ,

2x-7 = 37° and 4x-11 =77°
