This is a lot of calculation.

So we know that the sum of angles for any heptagon is 900, because heptagon can be divided into five non-overlapping triangles and sum of angles of each triangle is 180.

Now you just add up all angles and simplify the equation:

900 = (6x - 8) + 120 + (7x - 64) + (5x - 4) + 135 + (3x + 31) + (4x + 15)

900 = <span>25x + 225

Now it's just regular algebra equation. You can solve for x:

675 = 25x

x = </span>27

So the value of x is 27

A card is drawn from a 52 card deck any fair coin is flipped what is the probability of getting Jack and hits
Black_prince [1.1K]

Answer:

1/26

Step-by-step explanation:

There are 4 Jacks in every deck of cards, one for each suit. Therefore your chances of drawing a Jack, or any other card for that matter, are 4 in 52. So, the first probability for cards is 4/52.

Now, for the coin, the probability is 1/2.

So, the probability of getting Jack and hits is 4/52 X 1/2 = 1/26.
