Answer:
zero and one-hundred eighteen-thousandths
The length of side BD, given that AD = 5 and CD = 20 is 10 (Option A)
<h3>Data obtained from the question</h3>
- Length of side AD = 5
- Length of side CD = 20
- Length of side BD =?
<h3>How to determine the length of side BD</h3>
Since the triangles are similar, we can obtain the length of side BD as illustrated below:
CD / BD = BD / AD
20 / BD = BD / 5
Cross multiply
BD × BD = 20 × 5
BD² = 100
Take the square root of both sides
BD = √100
BD = 10
Thus, the length of side BD is 10

Answer with explanation:
Given: △ABC is an isosceles triangle with legs AB and AC.Also, △A Y X is also an isosceles triangle with legs A Y and AX.
To Prove: △ABC ~ △A Y X
Proof with Statement
1. △ABC is isosceles with legs AB and AC; △A Y X is also isosceles with legs A Y and AX.
2.AB ≅ AC and A Y ≅ AX.→definition of isosceles triangle
3.AB = AC and A Y = AX →→ definition of Congruency.
4.→→A Y × AC=AX × AC⇒[Multiplication property of equality]
5.≡A Y × AC=AX × AB⇒[Substitution property of equality]
----------------[Division property of equality]
7.Also, ∠A is common angle between two triangles.That is,
∠A=∠A------------[Reflexive property]
⇒Missing statement and Reason in the entire proof.
8.△ABC ~ △AYX----[SAS]

The random variable given in the accompanying table is discrete
<h3>How to determine the type of variable?</h3>
From the question, we can see that the table describes the number of girls
The number of girls can only take whole numbers i,e, 0, 1, 2, 3....
Variables represented like this are discrete variables
Hence, the random variable given in the accompanying table is discrete
