Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the length side AC

In the right triangle ABC

$tan(85.8^o)=\frac{AC}{AB}$ ----> by TOA (opposite side divided by the adjacent side)

substitute the given value

$tan(85.8^o)=\frac{AC}{24.8}$

$AC=tan(85.8^o)(24.8)$

$AC=337.7\ ft$

step 2

Find the length side CD (height of the tree)

In the right triangle ACD

$tan(10.4^o)=\frac{CD}{AC}$ ----> by TOA (opposite side divided by the adjacent side)

substitute the given value

$tan(10.4^o)=\frac{CD}{337.7}$

$CD=tan(10.4^o)(337.7)$

$CD=62.0\ ft$

I'm going to assume that's a multiplication not a decimal point.

$\sqrt{81 \cdot 49} = \sqrt{9 \cdot 9 \cdot 7 \cdot 7} = \sqrt{63 \cdot 63} = 63$

Answer: 63
