10 plus 4 equal 14 so you have to get the same sum for he other line since they are equal distances. 14 minus 5 is 9, so therefore x is equal to 9.
Answer:
<h2>129</h2>
Step-by-step explanation:
It should be noted that the rotation symmetry that an equilateral triangle has is 3.
<h3>What is rotational
symmetry?</h3>
It should be noted that rotational symmetry simply means when an object is rotated on its own axis.
In this case, it should be noted that the rotation symmetry that an equilateral triangle has is 3.
Also, the number of degrees that you can rotate the shape to carry it onto itself will be 60°, 120°, and 180°.

I did the problem and checked it on google and did the formula on paper. You would 628= 3.14 * x(squared) * 8, then you would undo everything, leaving you with x= 5
I tried my best, and I don't know if they wanted you to use pi or 3.14 so I hope this is correct :]
