The angles of a triangle are $latex (x+5)^{\circ}, (2x-3)^{\circ}$ and $latex (3x+4)^{\circ}.$ The value of x is :
[A]28
[B]29
[C]30
[D]31

29
Sum of angles of a triangle $latex = 180^{\circ}$
$latex \therefore x+5+2x-3+3x+4 = 180^{\circ}$
$latex => 6x+6 = 180^{\circ}$
$latex => 6x = 180 – 6 = 174^{\circ}$
$latex => x = \frac{174}{6} = 29&s=1$
Hence option [B] is correct answer.
