To find the length of the tree, x we use trigonometric ratio
[tex]\tan \text{ 44 =}\frac{opposite}{\text{adjacent}}[/tex][tex]\begin{gathered} \text{opposite = x } \\ \text{adjacent = 90ft} \\ \text{tan 44=}\frac{x}{90} \end{gathered}[/tex][tex]\begin{gathered} \text{Tan 44 x 90 = x} \\ x\text{ = 86.912 ft} \end{gathered}[/tex]The height of the tree= 86.912ft
