Answer:

  • b) cos∠S

Step-by-step explanation:

sin ∠R = SQ/SR

This is same as:

  • cos S

Correct option is b)

cos<Q

Lets do

[tex]\\ \sf\longmapsto sin<R=\dfrac{P}{H}[/tex]

[tex]\\ \sf\longmapsto sin<R=\dfrac{SQ}{SR}[/tex]

Now

[tex]\\ \sf\longmapsto cos<Q=\dfrac{B}{H}[/tex]

[tex]\\ \sf\longmapsto cos<Q=\dfrac{SQ}{SR}[/tex]
