Please help!
Hunter-Best [27]

Answer:

There is a 1/8 chance.

If there are 4 cards in the deck, and one three card, it makes it a 1/4 chance of picking the card the first time.

The probability stays the second time you pull out a card.

So, you would do the equation 1/4 * 1/4, which is 1/8. That is the answer.

Find the measure of the indicated angles below.Drag the points to show the measure of the four angles
horrorfan [7]
<h2>Answer</h2>

A. Angle E = 113°

B. x = 16°

<h2>Explain</h2>

<u>Number A</u>

92 + 70 + 85 + ? = 360

162 + 85 + ? = 360

247 + ? = 360

? = 360 - 247

? = 113°

<u>Number B</u>

108 + 84 + ( x + 30 ) + ( 2x + 18 ) = 360

(180 + 84 + 30 + 18) + (x + 2x) = 360

312 + 3x = 360

3x = 360 - 312

3x = 48

x = 48/3

x = 16°
