Emily (who is 5.5 feet tall) wants to measure the height of a tree in the
serg [7]

Answer:

YES

Explanation:

Here apply the formula for tangent of an angle to find height of the tree

Distance from house to tree is 100 ft = adjacent side

Tan ∅ = opposite side/adjacent side

Tan 46.4° = height of tree/100

h= 100 tan 46.4° = 105.01 ft

Given height of Emily is 5.5 ft, add this to 105.01 to find total height of the tree

=105.01 + 5.5 =110.51 ft

The tree is tall (110.51 ft) enough to hit her home which is 100 ft away from the tree.
