Which relationship exists between the two angles? What is the value of x? Find the measure of each angle. A) vertical angles; x = 3; 76 degrees; 76 degrees B) alternate exterior angles; x = 5; 116 degrees; 64 degrees C) corresponding angles: x = 7; 156 degrees; 156 degrees D) alternate exterior angles; x = 5; 116 degrees; 116 degrees Eliminate

Answers

Answer:

Option D.

Step-by-step explanation:

Diagram is missing, let as consider the diagram of this question is shown below.

If a transversal line intersect two parallel lines, then the alternate exterior angles are equal.

From the given figure it is clear that both angles alternate exterior angles. It means measure of both angles are equal.

$21x+11=20x+16$

Subtract 20x from both sides.

$21x+11-20x=20x+16-20x$

$x+11=16$

Subtract 11 from both sides.

$x+11-11=16-11$

$x=5$

The value of x is 5.

Measure of each angle is

$21x+11=21(5)+11=116^(\circ)$

$20x+16=20(5)+16=116^(\circ)$

Therefore, the correct option is D.

Answer:

D is the correct answer

Round each number to the nearest ten. What is the best estimate for the answer to 343.42 – 39.87?

Answers

The original answer for that question would be 303.55. The best estimate when you round to the nearest tenth the approximate answer would be 303.6 because the 5 in the hundredths place rounds the 5 in the tenths place to a 6. So the approximate answer would be 303.6....hope this helps.

with the nearest ten tha answer would be 300 because 340-40=300 and to the nearest thenth is would be 303.5 because 343.4-39.9=303.5

dessert choices: a cake or a shake, each available in vanilla or strawberry flavors

Answers

Answer:

The first answer is the correct choice.

Step-by-step explanation:

For this, there are two initial options. A cake or a shake. This means that there are two different trees that need to exist. One for Cakes and one for shakes.

Each of these trees needs to have the options of having vanilla and strawberry.

The first answer is the only one that follows this criteria

Step-by-step explanation:

A type of cell reproduces by splitting itself in half. One cell becomes 2 cells, 2 cells become 4 cells, and 4 cells become 8 cells. What type of sequence does the number of cells represent, and why? It represents an arithmetic sequence because it has a common difference of 2. It represents an arithmetic sequence because it has a common difference of 1/2. It represents a geometric sequence because it has a common ratio of 1/2. It represents a geometric sequence because it has a common ratio of 2.

Answers

It represents a geometric sequence because it has a common ratio of 2.

In fact, a sequence is said to be geometric if any two adjacent elements are in the same ratio. In other words, if you choose any index $n \in \mathbb{N}$ and consider the two consecutive terms $a_n$ and $a_(n+1)$ , you have

$(a_(n+1))/(a_n) = r$

no matter which index you chose. In your case, the next term in the sequence is always the double of the previous one, so the ratio between two consecutive terms is always 2, and the series is geometric with common ratio 2

Answer:

on edge 2021, your answer would be D.) It represents a geometric sequence because it has a common ratio of two.
