Answer:

1. $\dfrac{AD}{DB}+1=\dfrac{CE}{EB}+1$

2. Addition property of equality

Step-by-step explanation:

In triangle ABC,

$\dfrac{AD}{DB}=\dfrac{CE}{EB}.$

The addition property of equality states that if the same amount is added to both sides of an equation, then the equality is still true.

Use addition property of equality, add 1 to both sides of previouse equality:

$\dfrac{AD}{DB}=\dfrac{CE}{EB}\\ \\\dfrac{AD}{DB}+1=\dfrac{CE}{EB}+1\\ \\\dfrac{AD+DB}{DB}=\dfrac{CE+EB}{EB}$

Which congruence theorem can be used to prove △BDA ≅ △DBC? Triangles B D A and D B C share side D B. Angles C B D and A D B are

Tomtit [17]

Answer:

A. Hypotenuse-leg (HL) congruence.

HL, when you have 2 right triangles and their hypotenuses are congruent you are able to say HL

Step-by-step explanation:

We know that the hypotenuse-leg theorem states that if the hypotenuse and one leg of a right triangle are congruent to hypotenuse and corresponding leg of another right triangle, then the triangles are congruent.

hypotenuse(AB) of △BDA equals to hypotenuse (CD) of △DBC.

BDA and DBC share a common side DB.

Using Pythagorean theorem we will get,

$CD^{2}=DB^{2}+BC^{2}...(1) \\\\AB^{2}=DB^{2}+AD^{2}...(2)$

We have been given that CD=AB, Upon using this information we will get,

$DB^{2}+BC^{2}=DB^{2}+AD^{2}$

Upon subtracting $DB^{2}$ from both sides of our equation we will get,

$BC^{2}=AD^{2}\\\\BC=AD$

<h3>Therefore, by HL congruence △BDA ≅ △DBC.</h3>

Check each set that includes the number shown.

zavuch27 [327]

Answer:

Fourth option.

Sixth option.

Step-by-step explanation:

We know that:

- Any number you can find on the number line, is a Real number.

- Integers contains positive numbers, negative numbers and zero. Every Integer is a Rational number.

- A Rational number is that number that can be written in the following form:

$\frac{a}{b}$

Where "a" and "b" are integers ( $b\neq 0$ ).

- An Irrational number cannot be written as a simple fraction.

- A Whole number is any of the numbers { ${0, 1, 2, 3...}$ }. Every Whole number is a Rational number.

- Natural numbers contain the set of positive integers{ ${1, 2, 3...}$ } or to the set of nonnegative integers { ${0, 1, 2, 3...}$ }, Every Natural number is a Rational number.

Based on this, since $\frac{5}{9}$ is in the form $\frac{a}{b}$ where $a=5$ and $b=9$ , it is a Rational Number and therefore a Real number.
