Explanation:
We know that, complement angle is;
=) (90-x)°
A/q
Let the angle be x.
=) x= 2(90-x)°- 30
=) x= 180° - 2x -30
=) x+2x = 180 -30
=) 3x = 150
=) x= 150/3
=) x= 50°
Thus,
The angle is 50°.

Step-by-step explanation:
Let the compliment angle be 'a'
2a-30°=90°-a
2a+a=90°+30°
3a=120°
a=40°
therefore, the angles are 40° and 50°
