Answer:
you have to do 52 divided by cos of 38 to get the answer of 65.99ft
Answer:
45
Step-by-step explanation:
There are 10 points to choose as "starting points" and 9 points to connect them to so you would think that the answer is 10 * 9 = 90. However, this is incorrect as it is over-counting by a factor of 2. Suppose we have two points A and B. Using this method, 2 of the 90 line segments would be AB and BA but AB and BA are the same line segment. Therefore, the answer is 90 / 2 = 45.

Answer: 9 feet, 22 feet and 23 feet
Step-by-step explanation:
Let the smallest side be x.
The middle length side is 4feet greater than twice the length of the smallest side. This will be:
= (2 × x) + 4 = 2x + 4
The longest side is 4feet less than 3 times the length of the smallest side. This will be:
= (3 × x) - 4 = 3x - 4
Perimeter = x + 2x + 4 + 3x - 4
x + 2x + 4 + 3x - 4 = 54
Collect like terms
6x = 54
x = 54/6
x = 9
The three sides are
Smallest side = 9 feet
Middle side = 2x + 4 = 2(9) + 4 = 18+4 = 22 feet
Longest side = 3x - 4 = 3(9) - 4 = 27 - 4 = 23feet
