Use the trig ratio which gives you the most information. Here we have opposite and hypotenuse relative to angle x, so think sin( x ) = 14.1 / 27.9
Now we want to solve for x, but x is stuck inside the sine function
So how do we do this?
We can 'undo' the sine function by using the inverse sine. apply the inverse sin to both sides of the equation.
sin^-1 ( sin(x) ) = sin^-1 ( 14.1 / 27.9)
<span>The left side 'cancels' , leaving you with x </span>
<span>x = sin^-1 ( 14.1 / 27.9)
</span><span>Now you need a calculator.
</span>Make sure you are in degree mode.
<span>Calculators can give you answer in radian or degree.
</span><span>If you get a decimal answer, you are probably in radian mode.
</span>Round up if you want nearest hundredth
<span>30.3563 ≈ 30.36
</span>Or you can round to the nearest tenth
30.36 ≈ 30.4
Hope this helps! :)
