write this equation in polar form. round theta to the nearest tenth?

Question

5 = y + 2X

if you could show the steps, I would really really appreciate it

Answer 1

x= rcos(theta)
y=r sin(theta)
5= rsin(theta) + 2rcos(theta)

Answer 2

To convert the Cartesian equation of the line

2x + y = 5

into polar form use the identities.

x = r cosθ
y = r sinθ

We have:

2x + y = 2rcosθ + rsinθ = 5

r(2cosθ + sinθ) = 5

r = 5 / (2cosθ + sinθ)

There is no need to solve for θ. As θ ranges over its values the line is drawn.
