Question

If #sin theta = 1/4, then cos(90degrees - theta) =?

Explanation please?

Answer 1

`cos(90^@-theta)=1/4`

Explanation:

For all angles `A`, `cos(90^@-A)=sinA`

Hence `cos(90^@-theta)=sintheta=1/4`

Answer 2

`1/4`

Explanation:

`"using the "color(blue)"trigonometric identity"`

`•color(white)(x)cos(90-theta)^@=sintheta`

`rArrcos(90-theta)=sintheta=1/4`
