- we know that the sum of all angles of a triangle is equal to 180 degrees, so          4x+5x+9x=180 degrees                                                                                               18x=180 degrees                                                                                                                   x=10                                                                                                        so, 4x= 4*10=40, 5x= 5*10=50 and 9x= 9*10=90                                                   so the angles of the triangle are 40 degrees, 50 degrees, and 90 degrees.   so the triangle has all the sides unequal.                                                                hence, the triangle is a scalene  triangle
