What is Triangle?

A triangle is a three sided polygon , which has three vertices.

Given that;

In ΔEFG,

EG is extended through point G to point H.

m ∠EFG = (2x + 1)°

m ∠FGH = (6x + 2)°

m ∠GEF = (x + 19)°

Here, m ∠FGH is an exterior angle of ΔEFG.

And, m ∠EFG and m ∠GEF are interior angles of ΔEFG.

Since, Sum of two interior angle is equal to the value of an exterior angle.

Hence, We can formulate;

(2x + 1)° + (x + 19)° = (6x + 2)°

Solve as;

2x + 1 + x + 19 = 6x + 2

3x + 20 = 6x + 2

Subtract 3x both side;

3x + 20 - 3x = 6x + 2 - 3x

20 = 3x + 2

3x + 2 = 20

Subtract 2 both side;

3x + 2 - 2 = 20 - 2

3x = 18

Divide by 3;

x = 6

Thus, Value of m ∠GEF = (x + 19)° = (6 + 19)° = 25°

Therefore, The measure of angle GEF is 25°.

Answer:

20%

Step-by-step explanation:

Percentage discount on the cost of the sofa = 20%

Percentage discount = (Absolute discount / Cost price) × 100

Given,

             Cost price =  $600

Absolute discount  =  Cost price - Selling price

Absolute discount  =  $600 - $480

                                = $120

Percentage discount = (Absolute discount / Cost price) × 100

                                   = (120/600) × 100

                                   = 120/6

                                   = 20%

Hence, percentage discount on the cost of the sofa = 20% .

So sorry I replied so late but I'll leave the answer here just in case.

Answer:

7. Domain: [0,30]  Range: [0,7]

8. f(20) = 4.67 or 4 2/3; After 20 seconds, the squirrel is 4.67 meters away from the camera.

9. x = 1.25 and x = 21.43; The quirrel is 4 meters away from the camera at 1.25 seconds and 21.43 seconds.

10. At 2.5 and 19.29 seconds

11. 10 seconds

12. The squirrel went to the back of the camera, away from its line of view.

Step-by-step explanation:

7. The line is between 0 and 30 on the x-axis and is between 0 and 7 on the y-axis.

8. The slope of the third part of the line is not a whole number, so you need to calculate it. The rise is -7 meters and run is 15 seconds, so the slope is -7/15. Plugin -7/15 into the slope-intercept form (y = mx+b) and the equation is f(x) = -7/15 x+14. Plugin x=20 into the equation:

f(20) = -7/15(20)+14

f(20) = -9.33+14

f(20) = 4.67

9. The first slope of the graph will also need to be calculated. Rise is 7-3 (4) and the run is 5. Slope = rise/run = 4/5 = 0.8. Plugin the slope into y = mx+b with the y-intercept, and the equation is f(x) = 0.8x+3. Replace f(x) with 4 and solve the equation.

4 = 0.8x+3

1 = 0.8x

x = 1.25

There is another x value that matches with f(x) = 4 in the third part of the graph, so we'll use the slope-intercept form for the previous question for this one.

4 = -7/15 x+14

-10 = -7/15 x

x = 21.43

10. The squirel is 5 meters away from the camera twice, so we'll be using the same equations for the previous question.

5 = 0.8x+3

2 = 0.8x

x = 2.5

5 = -7/15 x+14

-9 = -7/15 x

x = 19.29

11. The squirrel is 7 meters away between 5 and 15 seconds. 15-5 = 10.

12. The squirrel most likely went somehwere where the camera can't see it, and it's probably the back of it.

Answer:

the distance is 12 units

Step-by-step explanation:

5 and 5 are the same so we don't use those digits,

-6 and 6 are different so we use them

since - 6 and 6 are both in different quadrants we take the absolute value of both of them and add,

|-6| + |6| = |6| + |6| = 12,

therefore the distance between C: (5,-6) and D: (5,6) is 12 units. hope i helped you (and could i have brainliest if possible?)

===========================================================

Explanation:

The x coordinates are the same (both are 5), so we just focus on the y coordinates.

The y coordinates are y = -6 and y = 6. Subtract the two values and apply absolute value to find the distance. Let's say A = -6 and B = 6.

|A-B| = |-6-6| = |-12| = 12

or we could say

|B-A| = |6-(-6)| = |6+6| = |12| = 12

Either way, we get the same answer. The order of subtraction doesn't matter if we apply absolute value.

On a graph, plotting the two points (5,-6) and (5,6) will show that there's 12 units of space between them.

--------------

If you wanted, you could apply the distance formula like so:

(x1,y1) = (5,-6)

(x2,y2) = (5,6)

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(5-5)^2 + (-6-6)^2}\\\\d = \sqrt{(0)^2 + (-12)^2}\\\\d = \sqrt{0 + 144}\\\\d = \sqrt{144}\\\\d = 12\\\\[/tex]

Though in my opinion, I think the distance formula is overkill for this situation.
