4-3i is the complex conjugate
Answer:
756.748
Step-by-step explanation:
5.
3x - 1 = x + 9
Subtract x on both sides
2x - 1 = 9
Add one on both sides.

Divide by 2 to get the x.
x = 5
Hope this helps!
Angles PQT and RQS are vertical angles and angles PQR and TQS are vertical angles.
angle PQS and TQR are straight angles
angles TQP and PQR form a linear pair. they are also adjacent by default. the other angles have these same features.
that should bout do it. hope it helped!
