It is a decrease and it is a decrease of 10 percent.
In a typical 30-60-90 triangle (which happens to be a right triangle, by the way), the sides, in increasing order, would be multiples of 1, sqrt(3) and 2.
Here, sqrt(3) is the longer leg (it's longer than 1).
Thus, the ratio of the length of the longer leg to the length of the hypotenuse
is sqrt(3)

18x - 9 = 72 are the equations
B=160+ 5c
b= 304- 3c
160+5c=304-3c
+3c +3c
160+8c=304
-160 -160
8c= 144
c=18
Answer:
2√21
Step-by-step explanation:
√81 is √4 times √21
Since √4 is a perfect square, √4 = 2
We are left with 2 times √21
2√21
