Answer:

<h2>Segment AD is 4, and segment AE is 2.</h2>

Step-by-step explanation:

The given triangle is attached.

In this problem we have two proportional triangles. We know that because it can be applied the theorem of Thales, which is about similarities, it describes the ratio between proportional segment, and this happens when we have a pairs of parralles crossed by transversal, as we have here.

So, if AB = 8 and AC = 4, which belong to the bigger triangle. That means the smaller must be in the same ratio, that is, one side must be half the other one. SO, from this proportion we know that if AD = 4, then AE = 2, and this is the statement we would need to prove that DE is half of the length of BC.

Actually, from the given graph and the given values, we already know that the ratio of this proportional figures is 1/2.

Therefore, the right answer is "Segment AD is 4, and segment AE is 2", because it represents the same proportion that the given one, and gives the proportion we want to find.

A diagram would be nice. The quick answer is C.

The first answer makes AE 8 which is twice as long as AC. I don't think the intent of the question is to use an external point.

The second one is also incorrect. This time E is in a place such that it makes AC and AE both equal and that too isn't possible.

The third one is the answer because D and E are both 1/2 the distance between the end point of the line containing them.

D is wrong because E is the midpoint of AC but D is not the midpoint of AB.

Please help me this looks easy but I don’t understand it tho

Let's call the unknown amount of money <em>x</em>

Betty spend 5/12 of her money (5/12)x and had 42 dollars left. Translated,

x - \frac 5{12} x = 42

Solving,

x(1 - \frac 5{12}) = 42

\frac{7}{12} x = 42

x =  \dfrac{12}{7} \cdot 42 = 72

Answer: $72

Find the length of a square whose area is 0.0084m​
TiliK225 [7]

Answer:

.091651514m

Step-by-step explanation:

The area of a square is found by

A = s^2 where s is the side length

.0084 = s^2

Take the square root of each side

\sqrt{.0084} = \sqrt{s^2}

.091651514 = s
