To solve this problem, we can use trigonometry. Let's label the trees as Tree A and Tree B, with Tree A being the taller tree.Step 1: Draw a diagram to represent the situation. Place the person halfway between the two trees, with the angle of elevation to the top of Tree A being
and the angle of elevation to the top of Tree B being
.Step 2: Use the tangent function to find the height of each tree. The tangent of an angle in a right triangle is equal to the opposite side divided by the adjacent side.For Tree A:
For Tree B:
Step 3: Since the person is standing halfway between the two trees, the distance from the person to each tree is the same. Let's call this distance
.For Tree A:
For Tree B:
Step 4: Solve for the height of each tree.Height of Tree A =
Height of Tree B =
Step 5: Calculate the difference in height between the two trees.Difference in height = Height of Tree A - Height of Tree BTherefore, the one tree is
taller than the other.
