## Homework Statement

Can someone please explain to me how parallax works?

I don't understand how the angle of parallax is measured

Question to help: Astronomers measuring the parallax angle to Planet X found that the angle measured after 6 months was 1.52 arcsec different from the initial measurement

Angle theta is angle (Earth-Jan)-Star-(Earth-July)

They then said that angle theta is 1.52 BUT I don't see how, can someone please provide a diagram

## Homework Equations

I can complete question knowing the angle theta is 1.52. I just don't understand why it is 1.52
