Question

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

Answer 1

Answer:

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=\frac{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:

$A=16.26\degree$
