If 0 Degrees Greater Than Or Equal To 0 90 Degrees And Cos 1115 What Is The Value Of Sin 900 class=

Answer :

We have to use the following trigonometric identity

[tex]\sin (90-\theta)=\cos \theta[/tex]

Given that

[tex]\cos \theta=\frac{11}{15}[/tex]

We just have to substitute

[tex]\sin (90-\theta)=\cos \theta=\frac{11}{15}[/tex]

Hence, the answer is A.
