Question

Cos 0 = 12/15. find sin 0.

Answer 1

Answer:9/15

Explanation:

Answer 2

`sin \theta = (3)/(5)`

Explanation:

`cos \theta = (12)/(15)\\\\cos^2 \theta = 1 - sin^2 \theta\\\\sin^2\theta = 1 - cos^2 \theta\\\\`

`= 1 - ((12)/(15))^2\\\\= 1 - (144)/(225)\\\\= (225 - 144)/(225)\\\\=(81)/(225)`

`sin \theta = \sqrt{(81)/(225)} = (9)/(15) = (3)/(5)`
