Question

Help! This one right here I didn’t learn please

Answer 1

x could be the opposite or adjacent side ( sin or cos ) but it will still give you the same answer

Explanation:

sin Ф = opp/hyp

sin 53 = x/10

10 sin 53 = x

x = 7.99

cos Ф = adj/hyp

cos 37 = x/10

10 cos 37 = x

x = 7.99

Answer 2

For this case we have to define trigonometric properties of rectangular triangles that, the sine of an angle is given by the leg opposite the angle on the hypotenuse of the triangle. So:

`Sin (53) = \frac {x} {10}`

We clear x:

`x = 10 * without (53)\\x = 10 * 0.79863551\\x = 7,986,351`

Rounding:

`x = 8`

ANswer:

8.0
