A 20-foot ladder is leaning against a tree. The bottom of the ladder is 12 feet away from the bottom of the tree. Approximately
arsen [322]
Pythagorean theorem is a^2 + b^2 = c^2. the hypotenuse is always the longest, so lets plug in the values.

a^2 + 12^2 = 20^2
if we simplify, we get a^2 + 144 = 400

then subtract 400-144 = 256
then find the sq. root of 256 = 16.

the answer is 16 feet

HELLPPPPP PLEASE!!!!! ILL MARK YOU BRAINLIEST
Keith_Richards [23]

Answer: four raised to the one third power

Step-by-step explanation:

According to the written description, we have the following expression:

\sqrt{\frac{4}{\sqrt[3]{4}}}

Which can also be written as:

(\frac{4}{4^{\frac{1}{3}}})^{\frac{1}{2}}

Let's work with this, taking into account the rules of multiplication and division of power with the same base:

(4^{1-\frac{1}{3}} )^{\frac{1}{2}}=(4^{\frac{2}{3}})^{\frac{1}{2}}

Multiplying the exponents:

4^{\frac{1}{3}} This is read as "four raised to the one third power"
