c. 28

c. 28

Step-by-step explanation:

Use Pythagorean theorem to find the leg of the right triangles.

a² + 12² = 15²

a² + 144 = 225

a² = 81

a = 9

So the value of x is:

x = 9 + 10 + 9

x = 28

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

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.
