Answer:

$log311y=log311+logy$

Step-by-step explanation:

We can use the property of logarithms of sum of logarithms:

$log_{b} (M*N)=log_{b} M+log_{b}N$

So, if we consider $M=311$ and $N=y$

We replace

$log311y=log311+logy$

At a certain time of day, the angle of elevation of the sun is 80degree. Find the height of a tree whose shadow is 44 feet long.

Arte-miy333 [17]

The height of the tree is 249.5 feet

<h3>How to determine the height of the tree?</h3>

The given parameters are:

Elevation angle = 80 degrees
Shadow length (L) = 44 feet

Let the height of the tree be x.

So, we have:

tan(80) = x/44

Multiply both sides by 44

x = 44 * tan(80)

Evaluate

x = 249.5

Hence, the height of the tree is 249.5 feet
