Answer:
Option (2)
Step-by-step explanation:
From the picture attached,
Let the rectangular coordinates (x, y) is represented by the polar coordinates (r, θ).
By applying Pythagoras theorem in ΔPAO,
PO² = AO² + AP²
r² = x² + y²
r =
By applying tangent rule in ΔAPO,
tanθ =
θ =
Therefore, Option 2 will be the correct option.

1. 15/3:3/3
2. 5:1
1. find the same denominator
2. divide by denominator
x^2-16
A= (b)(h)
A= (x+4)(x-4)
x^2-4^2
b=-3
-7b=21
-7b/-7=21/-7
