As Venus orbits the Sun, it appears to move away from the sun. At its greatest visual distance from the Sun..?

it forms a right angle with the Sun and Earth. We can used this to find the distance to Venus at that moment. If we measure the angle between the Sun and Venus (theta) as 0.809 radians and the distance to the Sun is known to ve 149,600 km, find the distance to Venus. And find the approximate distance between Earth and Venus when they are closest.
