Answer: C. Might not be congruent.

Step-by-step explanation:

In the given figure, we have two right triangles ΔABC and ΔDEF.

Also, it is given that,

\angle{A}=\angle{D}\\\angle{B}=\angle{E}\\\angle{C}=\angle{F}

So by, AAA similarity rule we can say  ΔABC and ΔDEF are similar.

But we cannot say it is congruent.

We need at-least one side equal in both triangles to prove it congruent.

For example :-All the equilateral triangles are similar but not congruent as the side lengths vary as per triangle but the angles remain same  60^{\circ}.

What is 4 2/3 as a decimal?<br> (I also need the work if not its ok)
quester [9]

Answer:

4.66

Step-by-step explanation:

Cause 4 would be 4.0 and then you take 100 and divide by the denominator and you get .33 for every 1/3. Since you have 2/3 it would be .66, then your answer would be 4.66

A baseball player which is based 35% of the time how many times can he expect to reach base and 150 at baths
Elan Coil [88]
He will expect to reach base 35%*150 times, or .35*150=52.5 times.  Although you cannot "reach base half of a time", this is the expected value for the amount of times he would reach base in this situation.

Please Help!!! I am totally lost!<br><br> Solve for x and find mangleABC.
kupik [55]
When something bisects an angle, it cuts that angle in half. This means that ray BD cuts angle ABC in half. Therefore, angle ABD, which is formed by cutting the angle in half, is equal to angle CBD, which is also formed by cutting the angle in half. Because of this, you have to set the equation equal to each other.

9x-18=5x+2

Combine like terms. Add 18 to both sides.

9x=5x+20

Combine like terms. Subtract 5x from both sides.

4x=20

Divide 4 on both sides.

x=5 degrees

A ladder is leaning up against a house. The ladder is 20 feet long and the base of the ladder is 12 feet away from the house. Ho
MrRa [10]

Answer:

16 feet

Step-by-step explanation:

The length of the ladder=20 feet

Distance from the base of the ladder to the house = 12 feet

You will notice that a wall is vertical and the ladder makes an angle with the horizontal ground(making it the hypotenuse). This is a right triangle problem.

To find the how far up the house can the ladder can reach, we simply find the third side of the right triangle.

From Pythagoras theorem

Hyp^2=Opp^2+Adj^2\\20^2=12^2+Adj^2\\Adj^2=400-144\\Adj^2=256\\Adj=\sqrt{256}=16

The third side of the right triangle is 16. Therefore the ladder leans 16 feet from the ground.
