This question is simple. Mark the letters first: the top of the tree is A, the top of B is B, the top of A is C, extend BC, make AD⊥BD pass through point A, cross BD at point D, extend AE to the ground, and the intersection point with the ground is E. Let AD=x, then X? 0? 5+(x+20)? 0? 5=4x? 0? 5, x= 10+ 10 times the root number three, and because the height of Party A and Party B 1.5m, AE = 1 1.5+10 times the root number three =1.
