Answer: I think its A
Step-by-step explanation:
X is equal to 15 explanation is that you subtract 180 for 165 to find x which is equal to 15
2 Answers: A) line symmetry and B) rotational symmetry
=====================================================
Explanation:
We have line symmetry because we can draw a vertical line down the center, and this is a mirror line. One half folds over the vertical line to match up with the other half. There are other lines of symmetry as well.
We also have rotational symmetry because we can rotate the figure some amount of degrees and have it line up with its original image. The before and after will be identical. This applies to any regular polygon.
A) you cannot combined square roots if the radicands aren't the same.
Its like variables. You can only add like terms. IE You cannot add 2x +3y.
Its the only rule that applies to the problem.
Answer:
b
Step-by-step explanation:
7 1/6= 7 8/48
3 5/8= 3 30/48
simplified, that would give us 3 26/48
if we simplify that again, it would give us b, 3 13/24
