Detailed Solution


Given angle is greater than 45º.
We have to find the angle which is complementary to the given angle.
We know that the complementary angles are the angles whose sum is 90°.
Assuming the given angle be 48° and the other angle be x°.
Now, taking the sum of the two angles,
48°+x°=90°
x°=90°-48°
x°=42°
Since, 42° is less than 45°.
Therefore, the other angle would be less than 45°.
Hence, option 3 is correct.
