Answer:
Sum of all angles is 720°
x=105
∠H=110°
∠I=100°
∠K=135°
Step-by-step explanation:
The sum of all inetrior angles is 720°
So,
140+105+130+(x+5)+(x-5)+(x+30)=720
375+3x+30=720
405+3x=720
3x=720-405
3x=315
∴x=105
∠H=x+5
∠H=105+5
∴∠H=110°
∠I=x-5
∠I=105-5
∴∠I=100°
∠K=x+30
∠K=105+30
∴∠K=135°
Answer:
What are you trying to do to my brain?
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.
For the first one is definitely 0.12
The second one I was having trouble with, but I know it is not .25 or .75. Looking at the leftover answers I would say .36 because I already used .12. Also .52 and .25 are the givens.
