Answer:
x=5 1/4
Step-by-step explanation:
2 1/4= 
---> divided by 3 to find 1/7x----> 
=1/7x---> x=21/4---> x=5 1/4
Answer:
1. Figure C has reflection symmetry.
2. A and D have reflection symmetry.
Step-by-step explanation:
1. When you cut the arrow horizontally, you get the same shape on each side.
2. When you divide them, you should have symmetry, meaning they are the same when divided/cut.
So, you already know that angle CBD is 68 degrees, and the complementary angle to angle CBD is angle CBA. These angles together make 180 degrees because segment DBA is a straight line consisting of angles CBD and CBA. 180-68(the angle you already know) is 112 degrees for angle CBA. Then you repeat this process to find the other angles
