Look at Figure 2. What is the measure of x ? ( Hint: you may need to use triangle ACE to help you;) notice the right angle??? NEED HELP ASAP PLEASE

Answers

Answer:

60°

Step-by-step explanation:

Let angle BAE = angle ACD = x

                                BCD  = AEC = 60°

EAC + FCA + ECF + AEC = EAC + x + 60° + 60° = 180°

                                 EAC = 60° - x

                                 BAC = EAC  + BAE = 60° - x + x = 60°

x=60° because of the reflection, hope this helps :)

C= 2 pi
R=2pi3
the formula for circumference is 2**r. so plug in the radius and it will be 2**3. that equals 6. I am not sure whether for your problem you’re supposed to multiply it by rounded pi, so the following answer is what you would get if you multiplied by pi, rounded. Now is infinite so we round it to 3.14. then multiply 6 by 3.14 and get 18.84 cm.

The point (7, 0) is reflected over the x-axis. What do you notice about the coordinates of the reflected point? Why is this?

Answers

Answer:

The coordinate stayed the same

Step-by-step explanation:

because when you reflect on the x-axis, the x-axis stays the same while the y-axis gets flipped. in this case, the coordinate is on the y-axis, or the y-axis is 0, and you can't flip 0 to get an opposite. the opposite of 0 is 0, so he coordinate stayed the same.

The value of reflected point is, (7, 0)

And, Any point on the line of reflection is invariant

What is Coordinates?

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

The point (7, 0) is reflected over the x-axis.

Hence,

The point (7, 0) becomes the point (7, 0) when reflected over the x-axis. That is, its coordinates do not change.

And, The point (7, 0) lies on the x-axis, so is on the line of reflection. Any point on the line of reflection is invariant--it doesn't move.

Hence, The transformation for reflection in the x-axis is ...

 (x, y) ⇒ (x, -y)

 (7, 0) ⇒ (7, 0) . . . . . . the opposite of 0 is 0

Thus, The value of reflected point is, (7, 0)

And, Any point on the line of reflection is invariant

Josh ran 14.8 km in the morning. After lunch, he continued running. When he finished the run, he had covered 31.1 km in all. Write an equation that can be used to find how far Josh ran after lunch.

Answers

14.8 + x =31.1
X equals how much he ran after lunch

Answer:

14.8 + x = 31.1

Step-by-step explanation:

This is the best equation to put as the answer.

If you want to solve it, this is how you would solve it.

14.8 + x = 31.1

Make it so that the variable x is by it's self.

14.8 + x - 14.8 = 31.1 - 14.8

x = 31.1 - 14.8

Now solve the subtraction problem.

x = 31.1 - 14.8 = 16.3

So, now you have your answer

x = 16.3

To make sure it's correct, use the addition method.

16.3 + 14.8 = 31.1
