Effectus [21]

Answer:

E. 2 1/2

E. 8.5 cm

C. 6 cm

Step-by-step explanation:

4............................

Scale factor = AE/AC = (4+6)/4 = 10/4 = 2.5

Correct option is E. 2 1/2

5............................

DE = ?

DE = √AD² - AE² = √15² - 10² = √125 = 5√3 ≈ 8.66

For measure of AD see next question (6)

Close option is E. 8.5 cm

6............................

AB = ?

AD/AB = 2.5 the scale factor as per question 4
(AB + 9)/AB = 2.5
2.5*AB = AB + 9
1.5*AB = 9
AB = 9/1.5
AB = 6 cm

Correct option C. 6 cm

5 ports Use absolute value to express the distance between -12 and -15 on the number line. |-12 - (-15) = -27

zloy xaker [14]

Answer:

$Distance = 3$

Step-by-step explanation:

Given

-12 and -15

Required

Solve the difference

The question you posted included the solution. However, the solution is incorrect;

The absolute difference is represented as:

$Difference = \vert a - b \vert$

In this case:

$a = -12$

$b = -15$

So, the distance is calculated as:

$Distance = |-12 - (-15)|$

Open bracket

$Distance = |-12 +15|$

$Distance = |3|$

$Distance = 3$

Given: measure 1, measure 2, measure 3, and measure 4 formed by two intersecting segments Prove: measure 1 and measure 3 are con

lesantik [10]

Step-by-step explanation:

The text below that are formatted in bold and underlined font are the solutions to the missing boxes in your given problem.

<h3>Explanation:</h3>

Given that ∠1, ∠2, ∠3, and ∠4 are formed by two intersecting segments, and that:

∠1 and ∠2 form a linear pair

∠2 and ∠3 form a linear pair

These linear pair relationships suggest that by the Linear Pair Postulate:

∠1 and ∠2 are supplementary. ⇒ Linear Pair Postulate

∠2 and ∠3 are supplementary. ⇒ Linear Pair Postulate

m∠2 + m∠ 3 = 180° ⇒ Definition of supplementary angles.

m∠1 + m∠3 = m∠2 + m∠ 3 ⇒ Substitution Property of Equality.

m∠1 = m∠3 ⇒ Subtraction Property of Equality.
