You have a triangle in which all three angles are known, together with one of the sides.

Use the sine rule to solve for the height of the tree. First solve for L, the side of the triangle opposite the 26° angle using

L/sin(26°) = 28/sin(57°)

The height, H of the tree is

H = L*cos(7°).

I get less than 15m for H.
