Answer 1

Step-by-step explanation:

Since it is MCQ i hope there is no problem in short trick.

Let all sides by equal to a

By putting a in all sides

cosP + sinQ = 1

sinP + cosQ = 1

This trick is valid bcoz there is no mention of a specific case, this should be valid for all quadrilaterals.

Seeing, P = Q = 90°

So P + Q = 180° = π.

This is applicable for all types of these problems.
