Question : In $\triangle \mathrm{ABC}$, $\angle \mathrm{ABC} = 90^{\circ}$, $\mathrm{BP}$ is drawn perpendicular to $\mathrm{AC}$. If $\angle \mathrm{BAP} = 50^{\circ},$ what is the value of $\angle \mathrm{PBC}?$
Option 1: $30^{\circ}$
Option 2: $45^{\circ}$
Option 3: $50^{\circ}$
Option 4: $60^{\circ}$
Correct Answer: $50^{\circ}$
Solution :
In right-angled $\triangle \mathrm{ABC}$, where $\angle \mathrm{ABC} = 90^{\circ}$, $\mathrm{BP}$ is drawn perpendicular to $\mathrm{AC}$. Given that $\angle \mathrm{BAP }= 50^{\circ}$ In $\triangle\mathrm{ ABC}$, $\mathrm{\angle C = 180^{\circ} - \angle A - \angle B = 180^{\circ} - 50^{\circ} - 90^{\circ} = 40^{\circ}}$ In $\mathrm{\triangle BPC}$,
