Lines CD and DE are tangent to circle A shown below: Lines CD and DE are tangent to circle A and intersect at point D. Arc CE measures 112 degrees. Point B lies on circle A. If Arc CE is 112°, what is the measure of ∠CDE? (4 points) Question 5 options: 1) 124° 2) 136° 3) 68° 4) 56°

Answers

Answer 1

Answer:

Option (3)

Step-by-step explanation:

By the theorem, angle between two tangents intersecting each other outside the circle is half of the difference between intercepted arcs.

From the figure attached,

Two tangents CD and DE are intersecting each other at point D outside the circle A.

Two intercepted arcs are minor arc CE and major arc CBE,

Measure of arc CE = 112°

Therefore, measure of major arc CBE = 360° - 112°

= 248°

m(∠CDE) = [tex]\frac{1}{2}(\text{arcCBE}-\text{arcCE})[/tex]

= [tex]\frac{1}{2}(248-112)[/tex]

= [tex]\frac{1}{2}\times 136[/tex]

= 68°

Option (3) will be the correct option.

- neither law can be used
- law of sines
- law of cosines
- both laws can be used

Answers

Answer:

Law of sines

Step-by-step explanation:

i took the test

The law of sines can be used to calculate the side h. Hence, option B is correct.

What is trigonometry?

The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.

For triangle FGH, angles F and G are known, as is the length of side h. The sin angle is the ratio of the perpendicular to the hypotenuse we can calculate one side by using the sine angle.

Hence, Hence, option B is correct.

What is the length of a day-night cycle? Is it the same everywhere on Earth?

12 hours - yes; because the sun rises and sets in the exact same place every day

relative to Earth.

12 hours - no; because depending on where you are on Earth, you have a

different amount of sunlight.

24 hours - yes; because the sun rises and sets in the exact same place every day

relative to Earth

24 hours - no; because depending on where you are on Earth, you have a

different amount of sunlight.

Answers

Answer: 24 hours - no; because depending on where you are on Earth, you have a different amount of sunlight.

Step-by-step explanation:

The day-night cycle is a complete day or a complete rotation of the earth around its axis. This takes 24 hours which is why 24 hours is the length of a full day.

People around the world however, do not get the same amount of sunlight or darkness and this is because of where they are on Earth. Due to the way the planet is tilted on its axis, some areas see sunlight more than other in a period and others see more darkness.

5x + 19.95 = 35
Solve x

Answers

Answer:

X = 3.01

Step-by-step explanation:

To solve for x, you first need to get x by itself. So you would minus 19.95 from both sides. Which would then be

5x = 15.05

Again x is not by itself so you would divide both sides by 5, the eqation would then be

x = 3.01

Which is the answer. If you want you can double check your work by putting the answer back in the eqaution.

5(3.01) + 19.95 = 35

If the statement is true that means you have the right answer

15.05 + 19.95 = 35

35 = 35

We are correct! Hope this helps with your question and how to do others like it.

Step-by-step explanation:

you can see that the two equations are almost identical except for the fact that one is multiplied by 7, but it isnt completely multiplied correctly so there would be no solutions.

Answer:

infinite solutions

Step-by-step explanation:

you can solve this by the elimination method. take the rover a equation and multiply it by -7 and then combine the equations. when you do this, you can see that either side equals 0 which means that there are infinite solutions.

-7(y= 1.5x - 6) which equals the equation below

-7y= -10.5x-42 then combine the other equation

7y=10.5x+42 and that equals
