In the right triangle shown, m\angle A=45\degreem∠A=45°m, angle, A, equals, 45, degree and AB = 12AB=12A, B, equals, 12. How long is BC

Answers

Answer 1
Answer:

Answer:

BC=6√(2)\ units

Step-by-step explanation:

In this problem i will assume that the side AB is the hypotenuse

The picture in the attached figure

we know that

In a right triangle, if one angle is 45 degrees, then the other angle complementary is equal to 45 degrees too

so

m\angle B=45^o

In the right triangle ABC

cos(B)=(BC)/(AB) ----> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

we have

cos(45^o)=(√(2))/(2)

AB=12\ units

substitute

BC=cos(B)(AB)

BC=(√(2))/(2)(12)=6√(2)\ units

An experiment consists of tossing a coin and drawing a card, with the card-drawing stage dependent on the result of the coin toss. If heads occurs, then a card is selected at random from the clubs and spades suits. If tails occurs, then a card is selected at random from the hearts and diamonds suits. What is the size of the sample space of this two-stage experiment?

Answers

The sample size of this two-stage experiment would be 1 fair coin and 1 deck of cards; 1 half deck of only clubs and spades, and one half deck of only hearts and diamonds.
