the sum of the angles in a triangle = 180

use the numbers of the ratio as the coefficients of x:

4x+5x+6x = 180; 15x = 180; x = 12

now just substitute x into the terms:

angle1 = 4(12) = 48

angle2 = 5(12) = 60

angle3 = 6(12) = 72

well a triangle has 180 degrees,

so one of them has to be 60 degrees (ratio 5)

and the other 2 just add/substract 12 so its

48:60:72.
