If it is the three angles of a triangle, then the angles add up to 180
4x + 5x + 6x = 180
15x = 180
x=12

Why does a triangle always equal 180 degrees? ... A rectangle has four 90 degree angles adding up to 360 degrees. Since the triangles are congruent each triangle has half as many degrees, namely 180. So this is true for any right triangle. Congruent angles have the same angle in degrees and radians.09/23/20
