3x + 4x + 5x = 180
12x = 180
x = 180/12
x = 15
3x = 45
4x = 60
5x = 75

so the smlllest ngle in degrees is 3x = 45 dgree

Ratio among the angles = 3:4:5
Let the angles be 3x, 4x and 5x.

Sum of angles of a triangle = 180
⇒ 3x + 4x + 5x = 180
⇒ 12x = 180
⇒ x = 180/12 = 15

Angles are(in degree):
3x = 15*3 = 45
4x = 15*4 = 60
5x = 15*5 = 75

greatest angle = 75 degree
