Answer:

22.5 , 90, 67.5

Step-by-step explanation:

given-

4 angle a = 12 angle c

angle a = 12 angle c / 4 = 3 angle c

3 angle b = 12 angle c

angle b=12angle c /3 = 4 angle c

so a=3c , b=4c

angle a + b+c=180 ( angle sum property of triangle)

3c+ 4c+ c=180

8c=180

c= 22.5

b=4c= 90

a =3c= 67.5
