let angles be 3x,
4x
A. T. Q.
4x+70=180 (linear pair)
4x=180-70
4x=110
3x+4x=180 (same)
7x=180
x=180
70
x=3
3x=9

Your ans is not correct.
3x + 4x=70
7x=70
X=10
Two of the angles are 30,40
Third angle is 30+40+a=180
a=180-70
a=110

Exterior angle = sum of two interior opposite angles
70=3x+4x
70=7x
x=10
First angle=30
Second angle=40
Third angle=180-30-40
=180-70=110
