A) \[40{}^\circ \]
B) \[60{}^\circ \]
C) \[37.5{}^\circ \]
D) \[70{}^\circ \]
Correct Answer: C
Solution :
(c): \[\angle A+\angle C=90{}^\circ :\]Now, let \[\angle A=7x;\] \[\angle C=5x\] Then, \[7x+5x=90{}^\circ \] \[\Rightarrow \,\,x=\frac{90{}^\circ }{12}=7.5{}^\circ \,\,\,\therefore \,\,\,\angle C=5x=37.5{}^\circ \]You need to login to perform this action.
