Question

enter the number that belongs in the green box

Answer 1

Set your calculator to degree mode.

`( \sin(29) )/(6.78) = ( \sin(x) )/(4)`

`6.78 \sin(x) = 4 \sin(29)`

`\sin(x) = (4 \sin(29) )/(6.78)`

`x = {sin}^( - 1) ( (4 \sin(29) )/(6.78) ) = 16.62`

The number that belongs in the green box is 16.62.
