Serjik [45]4 years ago
7 0

Answer:


Step-by-step explanation:

RT = sqrt(20^2 - 16^2)

RT = sqrt(400 - 256)

RT = sqrt(144)

RT = 12


SR/ST=  QR/QT

SR/12 = 20/16

SR = 12 x 20 / 16

SR = 240/16

SR = 15


answer is C.

15 Units

Find X please.......

So Angle 5 = 1x - 7 and angle 2 = -2x + 18. You can work out that angle 1 is the same as angle 5 because corresponding angles are equal. Then you know that angle 1 + angle 2 = 180 because angles on a straight line add to 180. So therefore 1x - 7 -2x + 18 = 180 so -1x + 11 = 180 so -x = 169 so x = -169. Hope this helps :)

26. A single card is drawn from a deck. Find the probability that the card is either red or a face card.
Lana71 [14]

Answer:

8/13

Step-by-step explanation:

There are total 26 red cards in the deck of 52 cards.

There are also 12 face cards in the deck ( which is 6 of them are red, while 6 of them are black)

Since we only need either one of them, 26 + 6 = 32

The probability of drawn a card that either red or a face card is 32/52

The simplest form of this fraction is 8/13.
