Question

plz answer this question​

Answer 1

Step-by-step explanation:

If Angle R is 90 Degree then the triangle PQR is Right Angled Triangle

1) Sin P=Perpendicular/Hypotenuse

  Sin P=QR/QP

2)Cos Q= Base/Hypotenuse

      Sin P= QR/QP

Note: side opposite to angle is called perpendiculer and longest  side is called hypotenuse and side on which both 90 degree and the other angle is made is called base
