Question

Use the give right triangle to find ratios. In reduced form, for sin A, cos A, and tan A

Answer 1

`\sin \theta=(opposite)/(hypotenuse)`

From the figure given, if theta = A

opposite = 28 and hypotenuse =53

substitute the values into the formula

`\sin A=(28)/(53)`

`\cos A=\frac{adjacent}{\text{hypotenuse}}`
`\cos A=(45)/(53)`
`\tan \theta=(opposite)/(adjacent)`
`\tan A=(28)/(45)`
