Assume the second number is x, then the other two are x - 2, x + 2

So x-2 + x + x + 2 = 51

-> x = 17

Nonamiya [84]

Answer:

Problem:

180-144=36

36/2=18

A=18

Step-by-step explanation:

The full area of half of a circle is equal to 180 degrees. To find the missing value of both A's you must take the full degrees of 180 and subtract 144 from 180. Next you have to take the remaining number and divide it by two because both of the missing value's are equivalent.

The 9 combinations that exist for two movements:

R,R
R,L

U,R *

U,U

Walker would only be able to make it to (1,1) with only 2 of these combinations.

So if he were only allowed to make two movements, his chances of arriving at (1,1) would be 2/9.
