Answer: 42, 69, 69 degrees
Step-by-step explanation:
Let the base angles be m degree each. Then the vertex angle is m-27
So
m+m+m-27=180
3m=207
m=69
So the angles are 42, 69 and 69

Answer:
let the base angle be x degree. then x -27
x+x+x-27=180
3x-27=180
3x=180+27
3x=207
x=207/3
x=69
each two angle is 69
69+69+x=180
138+x=180
x=180-138
x=42
