Question

Write the ratio for sin A.sin A=(Type an integer or a simplified fraction.)

Answer 1

To find sin A.

we know that,

In a right triangle, angle theta, we get

`\sin\theta=\frac{\text{ Opposite side}}{\text{ Hypotenuse}}`

Here, for an angle A, we get

Opposite side= 7

Hypotenuse= 25

Substitute the values, we get

`\sin A=(7)/(25)`
`\sin A=0.28`
`A=\sin^(-1)(0.28)`
`A=\sin^(-1)(0.28)\approx16.26\degree`
`A=16.26\degree`

Answer is:

`A=16.26\degree`
