Question

Which equation is correct

Answers choices
Sin G= 8/15
Cos G=8/15
Cos G=15/17
Sin G=15/17

Answer 1

For this case we have to define trigonometric relations of rectangular triangles that:

• The cosine of an angle is given by the leg adjacent to the angle on the hypotenuse of the triangle.

• The sine of an angle is given by the leg opposite the angle on the hypotenuse of the triangle.

Then, according to the figure we have:

`Sin (G) = \frac {15} {17}\\Cos (G) = \frac {8} {17}`

Answer:

`Sin (G) = \frac {15} {17}`
