1. Name two angles that are supplementary to ∠DOE. 2. - 1

Answers

Answer 1
Answer:

Two angles, namely ∠AOE and ∠COD, are supplementary to angle ∠DOE.

A pair of complementary angles consists of angles ∠BOC and ∠COD.

Two pairs of vertical angles are ∠AOE and ∠COD.

What are supplementary angles

When two angles are supplementary, it means that the sum of their measures is 180 degrees.

In this case, the angles ∠AOE and ∠COD are stated to be supplementary to angle ∠DOE. This implies that if you were to add the measures of ∠AOE and ∠COD together, their sum would be 180 degrees, which is the definition of supplementary angles.

Complementary angles are angles whose measures add up to 90 degrees. In the statement, the angles ∠BOC and ∠COD are identified as forming a pair of complementary angles.

Vertical angles are a pair of non-adjacent angles formed by intersecting lines. In the statement, the pairs of vertical angles are given as ∠AOE and ∠COD.

Variable g is 8 more than variable w. Variable g is also 2 less than w. Which of the following pairs of equations best models the relationship between g and w?g = 8w
g = w + 2

w = g + 8
w = g − 2

w = 8g
w = g + 2

g = w + 8
g = w − 2

Answers

If you would like to find a pair of equations that best models the relationship between g and w, you can do this using the following steps:

g is 8 more than w ... g = w + 8
g is 2 less than w ... g = w - 2

The correct result would be g = w + 8 and g = w - 2.

What is the difference in elevation between High Point (673 feet above sea level) and Low point (80 feet below sea level)?

Answers

Answer:

The difference in elevation between High Point and Low Point is of 753 feet.

Step-by-step explanation:

Since High Point is located at 673 feet above sea level (+673) and Low Point is located at 80 feet below sea level (-80), in order to know the difference in elevation between both points we have to do the following calculation:

673 - (-80) = Difference

673 + 80 = Difference

753 = Difference

The difference in elevation between High Point and Low Point is of 753 feet.
Difference is subtraction so 673-80 = 593. 593 is your answer. ;) Hope I helped.

Factor completely 9x2 − 25.

Answers

The required, 9x² - 25 can be factored completely as (3x + 5)(3x - 5).

To factor completely the expression 9x² - 25, we can use the difference of squares formula, which states that:

a² - b²= (a + b)(a - b)

In this case, we can recognize that 9x² is the square of 3x, and 25 is the square of 5. Applying the difference of squares formula, we have:

9x² - 25 = (3x)²- 5²

Using the formula, we can factor it as:

(3x + 5)(3x - 5)

Therefore, 9x² - 25 can be factored completely as (3x + 5)(3x - 5).
