r^2 + 15^2 + 15^2
r = sqrt (450)
tan O = 15/15 = 1
so O = 45 degrees
so polar form for 15 + 15i
= sqrt 450 ( cos 45 + i sin45) or
21.2 (cos 45 + i sin 45)
Answer:
Slope = 1
Step-by-step explanation:
Slope = change in y/change in x
= (8-5)/(5-2)
=3/3
Any real numbers , I think
k has a rotational symmetry
