Answer: No, they are not similar.</h3>
Technically, we don't have enough info so it could go either way.
==========================================================
Explanation:
We can see that the sides are proportional to each other, but we don't know anything about the angles. We need to know if the angles are the same. If they are, then the hexagons are similar. If the angles are different, then the figures are not similar.
Right now we simply don't have enough info. So they could be similar, or they may not be. The best answer (in my opinion) is "not enough info". However, your teacher likely wants you to pick one side or the other. We can't pick "similar" so it's best to go with "not similar" until more info comes along the way.
Lets solve for x.
0.8x = 50. - Remember that the jacket was 80% of the original price.
Thus, divide by x.
x = 50 / 0.8
x = 62.5
To find the radius, then, we insert 18 in for the circumference. So 18=2∏r. Solving for r gives 9/∏, or approximately 2.86 inches.
When you divide two fractions, you're actually multiplying one of them by the reciprocal of the other. First, find the reciprocal of the second fraction by flipping it upside down. Then, multiply it by the first fraction. (Numerator x numerator and denominator x denominator)

÷

Replace the second fraction with it's reciprocal

x

Multiply (-7 x 3 and 12 x 2)

Both 21 and 24 are divisible by three, so divide them by 3
