Can someone help me with this

  596.0 ft

Step-by-step explanation:

The relationship between the two legs of a right triangle and an acute angle is ...

  Tan = Opposite/Adjacent

The height (h) of the lighthouse is the side opposite the angles of elevation. If d is the distance between A and B, we can write two tangent relations:

  tan(14°) = h/770

  tan(8°) = h/(770 +d)

Equating expressions for h gives ...

  770·tan(14°) = (770 +d)·tan(8°)

  770(tan(14°) -tan(8°)) = d·tan(8°) . . . . subtract 770·tan(8°)

  d = 770·(tan(14°)/tan(8°) -1) . . . . . divide by the coefficient of d

  d ≈ 770·(1.7740609 -1) = 596.03

The distance from point A to point B is about 596.0 feet.
