A15 foot pole is leaning against a tree. the bottom of the pole is 8 feet away from the bottom of the tree. approximately how high up the tree does the top of the pole reach?

The top of the pole is approximately 13 feet high up the tree.

Step-by-step explanation:

The diagram for the given scenario is shown below.

From triangle ABC, A is the top of pole and B is the bottom of pole.

AC is the height of tree. BC is the distance of the  bottom of pole from the tree.

Given:

AB = 15 ft, BC = 8 ft

To find:

AC = ?

Since triangle ABC is right angled triangle, we apply Pythagoras Theorem to find the unknown side. So,

Therefore, the height of the tree is approximately 13 ft.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

i hope this is what you were looking for.
