A) \[30{}^\circ \]
B) \[45{}^\circ \]
C) \[90{}^\circ \]
D) \[180{}^\circ \]
Correct Answer: B
Solution :
(b): Let angle be \[\angle a\] : If its complementary \[\angle le\,\,(\theta )\] is same angle, then complement is also \[\angle a\] Their sum \[\angle a+\angle \theta =\angle a+\angle a=90{}^\circ \Rightarrow \angle a=45{}^\circ \]
