#4 = B
Explanation= Because C&A are the same angle measurement, and the 90 angle is along a straight line making the other angle 90, and the triangles share the same side the postulate you can use is AAS because you can prove that the triangles share 2 common angles and 1 common side

#5 = B
Explanation= Because the triangles already have 1 congruent angle, and 1 congruent side the only thing left we can prove is that because the triangles mirror each other, they have congruent opposite angles (may be called vertical angles) as well so they have 2 angles and 1 side in common which tells you to use AAS

An example of dependent events is drawing a red marble out of one jar and then drawing a
sladkih [1.3K]

Answer:

Second Option:

"green marble out of the same jar, without replacing the first marble"

Step-by-step explanation:

Two events r and s are independent if the probability that r occurs does not affect the probability that s occurs.

When choosing an object of some color b from a jar with n objects where there are x objects of the desired color b, the probability of obtaining 1 object of color b when randomly selecting an object from the jar is:

P_1 =\frac{x}{n}

If after taking the object it does <em>not return</em> it to the jar (without replacement) then, now the probability of obtaining an object of color b is:

P_2 = \frac{x-1}{n-1}   if the one selected in the first trial was the color b.

P_2 = \frac{x}{n-1}   if the one selected in the first test was not  the color b

Note that now the probability P <em>depends on the result obtained in the previous test.</em>

<em>This event is </em><em>dependent</em><em>.</em>

However, if by take object b in the first test, and the object is <em>returned</em> to the jar, and then the second test is made, then

P_1 = P_2.

The probability  does <em>not depend on the result of the first trial</em>. The same happens if the objects are taken from <em>different jars</em>.

<em>These would be </em><em>independent</em><em> events.</em>

Finally the correct option is the second option.

12m, and 8m what is the third angle of the tirangle
solong [7]
So we use pythagorean theorem.

a^2+b^2=c^2

Do you have the triangle drawn ? It matters what side we are solving for.

12m^2 + 8m^2 = c^2

c^2= 208

c= 14.42 m

I can solve for what you want, just need some information from you
