Add all three expressions up and set them equal to 180 degrees, because there are 180 degrees in a triangle.
The correct answer is the third option, which is:
6 inches²
The explanation is shown below:
1. You are working with the areas of the pentagons shown in the figure above. Therefore, the ratios are:
side1²/side2²=A1/A2
(7.5)²/(2.5)²=54/A2
Where A2 is the the area of the smaller pentagon.
2. Therefore, you have that the result is:
A2=6 inches² (As you can see, it is the third option mentioned above).
Answer:
The standard deviation of the numbers is 2.24
