Trigonometry!! Please Help picture attached

Answer 1

`\sin B=(3√(58))/(58)`

`\cos B=(7√(58))/(58)`

`\tan B=(3)/(7)`

Explanation:

The sine of an angle is the length of the opposite side divided by the length of the hypotenuse, which in this case is
`(3)/(√(58))=(3√(58))/(58)`. The cosine is the adjacent side divided by the hypotenuse, which in this case is
`(7)/(√(58))=(7√(58))/(58)`. The tangent is the length of the opposite side divided by the length of the adjacent side, which in this case is simply
`(3)/(7)`. Hope this helps!
