Answer 1

For this case we have that by definition of trigonometric relations that, the sine of an angle is equal to the opposite leg to the angle on the hypotenuse. So:

$Sin (36) = \frac {5} {x}$

Clearing x:

$x = \frac {5} {sin (36)}\\x =\frac {5} {0.58778525}\\x = 8.517887564$

Rounding off we have to:

$x = 8.51$
