ANSWER᭄
Let the required angle be x .
Thus,
The complement of the given angle will be (90° - x).
Also,
The supplement of the given angle will be (180° - x).
Now,
According to the question;
The supplement of the required angle is 4 times of its complement.
Thus,
=> (180° - x) = 4(90°- x)
=> 180° - x = 360° - 4x
=> 4x - x = 360° - 180°
=> 3x = 180°
=> x = 180°/3
=> x = 60°
Hence,
The required angle is 60°
