This illustration shows the angles from the cameras when looking at the right side of boulder B3. The angles shown from left to right are 110 degrees and 55 degrees.
This illustration shows the angles from the cameras when looking at the left edge of the hole H2. The angles shown from left to right are 65 degrees and 105 degrees.
What is the distance between hole H2 and boulder B3? Hint: You will have to use both the sine law and the cosine law.
