Final answer:
To solve for the height of the tree, use the proportion 6/h = 10/30. Cross-multiply and solve for h.
Step-by-step explanation:
To solve for the height of the tree, we can use the proportion 6/h = 10/30.
This proportion compares the height of the tree (h) to the known relationship between the values 6 and 10.
To find the value of h, we can cross-multiply and solve for h. Cross-multiplying gives us 6 * 30 = 10 * h, which simplifies to 180 = 10 * h.
Dividing both sides by 10 gives us h = 180/10, or h = 18.
