Question

What would y=
4.6
13.9
21.6

Answer 1

13.9 is the right answer :)

Explanation:

Answer 2

For this case we have to define trigonometric relations of rectangular triangles, that the tangent of an angle is given by the leg opposite the angle on the leg adjacent to the angle.

Then, according to the figure we have:

`tg (60) = \frac {y} {8}\\y = 8 * tg (60)\\y = 8 * 1.73205081\\y = 13,85640648`

Rounding the value we have that
`y = 13.9`
