Question

If 0 degrees greater than or equal to 0 90 degrees and cos = 11/15 what is the value of sin ( 90-0)

Answer 1

We have to use the following trigonometric identity

`\sin (90-\theta)=\cos \theta`

Given that

`\cos \theta=(11)/(15)`

We just have to substitute

`\sin (90-\theta)=\cos \theta=(11)/(15)`

Hence, the answer is A.
