Answer:

1/10

Step-by-step explanation:

There are 6 marbles in the bag. 3 out of 6 are green.

3/6 = 1/2

So, he has a 1/2 of picking a green marble.

After getting a green marble, Joe doesn’t replace it meaning there are now only 5 marbles in the bag.

Since there’s one red marble in the bag the chance of trying one is 1/5.

Now to find the chance or drawing a green and red marble you need to do the equation:

1/2 x 1/5

This equals 1/10.

The probability is 1/10

In the given figure, BAC = 90° and ABC = 45°. Prove that: AB = AC. ​
Amiraneli [1.4K]

Answer:

<h2>By angle sum property:</h2>

BAC+ABC+BCA=180°

90°+45°+x=180°

135°+x=180°

x=45°=BCA

<h2>since BCA=ABC=<u> </u>45° each </h2><h2>therefore,</h2>

AB=AC \\ (isosceles \: triangle \:  \\ theorem)

Determine the value of x for which rls if<br> .<br> m2i = 80 - X; and<br> mz2 = 90 - 2x<br> .
Slav-nsk [51]

Answer:

  x = 10

Step-by-step explanation:

For the lines to be parallel, the two angles must have the same measure:

  80 - x = 90 - 2x

  x = 10 . . . . . . . . . add 2x-80

The value of x must be 10 to make the lines parallel.
