Answer:
6+11i
Step-by-step explanation:
2+3i + 4+8i
Add the real parts
2+4 = 6
And the imaginary parts
3i+8i = 11i
The complex number is the real plus the imaginary
333+p/4=999
p/4=666
p=2664
A. 50.24
C=2πr=2·π·8=50.24
Answer: 11

If they are parallel then the 2 labelled angles sum to 180.
2x+50+5x-80=180
7x-30=180
7x=210
x=30
I only know 17 which it should be D
