Answer: There are only two sides in each coin that Olga flips. If the coin lands on heads or tails then both will have a different result as one of them will be revealed to Olga as the coin stops flipping. For example Jessica flips a coin and it lands on tails and heads will not be revealed.

Answer:

166

Step-by-step explanation:

If the four lines are tangent to the circle, know that:

NA = KA

AD = LD

LC = MC

MB = NB

The question stated that:

NA = 18 --> KA is also 18

BN = 11 --> MB is also 11

AD = 34 --> LD is also 34

BC = 31 --> MC is 20 (Because BC is BM + MC and BM is 11)

We can just add these numbers.

(18+18) + (11 + 11) + (20+20) + (34+34)

= 36 + 22 + 40 + 68

= 76 + 90

= 166

The perimeter of ABCD is 166.
