The scientist can use right triangle trigonometry to get the distance AC from the shooting star to the sun.

Using the cosine function, the scientist writes:

cos(x) = y/AC where x is the known angle, y is the known distance from Sun to Earth.

The scientist puts those values in for y and x and then solves for AC to get the Sun to Shooting Star distance.
