How would you simplify this polar equation to r=?

2=rcos(theta-20)

Would i divide the 2 by both sides?

Then how would i bring the r out?

Multiply R by both sides so that u have r equals the rest of the equation

r=2/cos(theta-20) -the equation of a line

why wouldnt it be cos(theta-20)/2?

We divide both sides by cos(theta-20)
