If x=3+bi, then

You know that
then

Two possible complex numbers satisfy these conditions:

As you can see the possible value of b is 2.
Answer: correct choice is A.
<span>We know Sin theta is given by Perpendicular/ hypotenuse.
Hence in this case the angle given is 30 degree and hypotenuse is given as 10 foot.
Hence Sin 30= P/ 10
1/2= P/10
Hence on solving value of P is 5.
Now we have to compute the theta value for Perpendicular as 5 and now the height of ramp is increased to 15 foot, hence hypotenuse is now 15 foot.
Hence Sin theta= 5/15
On taking inverse of Sin Theta we will get the theta value as 19.47.
Hence the angle of ramp should is 19.47 degrees.</span>
Yes it’s correct because 9 is x and if you substitute you do 9 x -9 which gives you y and is -81
