What is the length of line segment SR?

Step-by-step explanation:

Using Pythagorean theorem.

16^2 + (RT)^2 = 20^2

256 + (RT)^2 = 400

(RT)^2 = 144

RT = 12

Using altitude theorem to find ST:

16/12= 12/ST

16ST = 144

ST = 9

Using Pythagorean theorem again:

12^2 + 9^2 = SR^2

144 + 81 = SR^2

225 = SR^2

SR= 15

Final SR= 15

step-by-step explanation:

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.
