Question

How do you solve `c/sin60=3/sin75`?

Answer 1

`≈2.69" 2 decimal places"`

Explanation:

The first step is to `color(blue)"cross-multiply"`

`rArrcxxsin75^@=3xxsin60^@`

To solve for c, divide both sides by `sin75^@`

`(c cancel(sin75^@))/cancel(sin75^@)=(3sin60^@)/sin75^@`

`rArrc=(3sin60^@)/sin75^@`

`=2.69" to 2 decimal places"`
