x = 129

Step-by-step explanation:

Mathematically, the sum of interior angles of a polygon can be calculated using the formula;

(n-2)180

from the question given , n = 7 since the polygon has 7 sides

thus, we have it that

(7-2)180 = 5 * 180 = 900

Mathematically, by adding all the given interior angles, we can get the value of the total

We have this as;

900 = x + 131 + 119 + 125 + 133 + 125+ 138

900 = x + 771

x = 900-771

x = 129

answer: there are 453.592 grams in a pound.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
