Answer:
38.93857982... is a irrational because it is a non-terminating, non-repeating decimal.
Step-by-step explanation:
Irrational number: the number which cannot be represented in the form of p/q where p and q are integer and q not equal to 0. In other words a Irrational number is a non terminating non repeating decimal number.
x³ + 27 which can be written as x³ + 3³
It is in the form of a³ + b³ = ( a + b) ( a² - ab + b²)
so
x³ + 3³
= (x+ 3) (x² - x * 3 + 3²)
= ( x + 3 ) ( x² - 3x + 9)
Hope this helps you.

Applying the trigonometry ratio, TOA, the measurement that is closest to the height of the tree in feet is: D. 21
Recall:
Trigonometry ratios can be applied to solve any right triangle for missing side lengths or angles. They are denoted with the acronym, SOH CAH TOA.
Using trigonometry ratio, TOA, find the length of the side of the tree in the bigger triangle as follows:
tan 60 = x/9
x = tan 60 × 9
x = 15.6 ft
Height of the tree = 15.6 + 5.2 = 20.8 ft.
- In conclusion, applying the trigonometry ratio, TOA, the measurement that is closest to the height of the tree in feet is: D. 21
