Question

the angle of a triangle (3x) (2x-7) and (4x-10) find x

Answer 1

Hola

Here is your answer

3x + 2x - 7 + 4x - 10 = 180

Angle sum property of a triangle.

therefore, 9x - 17 = 180

9x = 180+17

9x = 197

x = 197/9

x = 21.888...

Answer 2

(3x) + (2x - 7) + (4x -10) = 180° (Angle Sum Property)

3x + 2x + 4x - 7 - 10 = 180°

9x - 17 = 180°

9x = 180° + 17

9x = 197°

x = 197°/9

x = 21.8°

Hope it helps :)
