Answer:
The area of △AON is one-sixth part of △ABC.
Step-by-step explanation:
Let the total area of △ABC be x.
Median divides the area of a triangle in two equal parts.
Since AM are CN are medians, therefore the area of △ACN, △BCN, △ABM and △ATM are equal, i.e., 
.
The intersection point of medians is called centroid of the triangle. A centroid divides the median in 2:1.
Since CN is median and O is the centroid of the triangle, therefore CO:ON is 2:1.
Draw a perpendicular on CN from A.
Therefore the area of △AON is one-third of △ACN.
The area of ANO is 
. Therefore the area of △AON is one-sixth part of △ABC.
Answer:
I don't have the answer to the first page but I do for the second.
Step-by-step explanation:
Use the Pythagorean theorem, A^2+B^2=c^2
2a. 13
2b. 15
2c. 50
2d. 4.5(Rounded to nearest tenth)
3. 10.8 ft
B=5
You need to get b by itself on the left side. 4b is multiplying 4 to b. You need to the opposite when you want the variable by itself. You would divide 4 to each side. 4 cancels out on the b so it turns into b. Then 4 divided by 20 is 5. B=5
