The correct rectangular equivalence of 3sqrt(2)·cis(7pi/4 ) is:
3sqrt(2)·cos( 7pi/4 ) + i·sqrt(2)·sin( 7pi/4 ) = 3 - 3i.
<h3>Where did David go wrong?</h3>
David mistakenly interchanged the Sin function and the Cos function when he was calculating the problem.
Hence the correct rectangular equivalence is:
3sqrt(2)·cos( 7pi/4 ) + i·sqrt(2)·sin( 7pi/4 ) = 3 - 3i.
<h3>What is rectangular equivalence?</h3>

Here is the answer for the question
When an angle is bisected, it is split into two halves. If the original angle of 119 degrees is bisected, each new angle will equal half of 119, which equals 59.5 degrees.
7 with 13 over 125 this is the mixed number form.
If I read the problem correctly, the answer should be D) 5.
The picture was blurry so I hope I read it right.
I hope this is correct and that it helps✨❤️
