Step-by-step explanation:
If Omar has $350 to spend on the garden he is designing, then he has possibility to buy 11 triangle stones and 26 border pieces, if the construction look like below, because 20×11 + 5×26 = 350.20×11+5×26=350.
So, the length of the path is 11×3 = 33 units, if the length of a side of such triangle is 1 unit.

Answer:
Step-by-step explanation:
4). By applying cosine rule for angle R,
cos(∠R) = 
cos(33°) = 
[Equation]
x = 19cos(33°)
= 8.39
5). By applying sine rule,
cos(20°) = 
cos(20°) = 
[Equation]
x = 
x = 15.96
6). By applying tangent rule,
tan(40°) = 
tan(40°) = [Equation]
x = 
x = 17.88

Given
Studying the rainfall on the first day of September, October, and November is not a random sample for studying the rainfall on the first day of each month for one year.
To explain why.
Explanation:
It is given that,
Studying the rainfall on the first day of September, October, and November is not a random sample for studying the rainfall on the first day of each month for one year.
The reason for Studying the rainfall on the first day of September, October, and November is not a random sample is, because these months are three specific months which means other months cannot be selected.
Hence, the answer is option b).
