The answer is A. I’m pretty sure
Answer:
(this might be wrong but if your desperate) 518
Step-by-step explanation:
1. 70+52=122
2. 640-122= 518
If a point
(
x
,
y
)
is written as
(
r
,
θ
)
in polar coordinates, then
x
=
r
o
s
θ
and
y
=
r
sin
θ
.
As such in polar form equation
x
=
−
3
can be written as
r
cos
θ
=
−
3
or
r
=
−
3
cos
θ
Actually the answer is B because answer doesn't include -3 so open circle on -3.
