1. angle addition post

2. 2x=56

The corresponding angles of the lines solved and the value of x = 28°

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line. The intersecting line is known as transversal line.

We can conclude three factors determining parallel lines ,

Alternate angles are equal

Corresponding angles are equal

Co-interior angles add up to 180°

Given data ,

Let the measure of ∠ELG = 124°

The measure of ∠ELD = 2x

∠ELG and ∠ELD are a linear pairs of angles

So , the measure of ∠ELG  + ∠ELD = 180°

On simplifying , we get

2x + 124° = 180°

Subtracting 124° on both sides , we get

2x = 56°

Divide by 2 on both sides , we get

x = 28°

Therefore , the value of x is 28°

Hence , the angle is x = 28°

Step-by-step explanation:

Answer:

This is because the shapes are dialations of each other

So PO and ML are the same side of the triangles but ML is dialated by a factor of 3.5 so that applies to the whole shape. So 21/3.5 = 6

Mickey simplified the expression below. He then checked his work by substituting 4 for x. He noticed his two values were not equal. What was Mickey’s error when simplifying?

Expression: 2x^2 - 4x - 9 - x^2 + 2x + 3

Simplified expression: x^2 - 6x - 6

ANSWER CHOICES:

Mickey should have added –4 and 2 when combining the coefficients of the x terms.

Mickey should have added 2 and 1 when combining the x^2 terms.

Mickey should have added 9 and 3 when combining the constant terms.

Mickey should have added –4 and –1 when combining the x terms.

Answer

Mickey should have added –4 and 2 when combining the coefficients of the x terms.

Explanation:

To simplify an expression means to group and organize the expression in a such a way that it becomes more understandable, and can now easily be solved

Given the expression 2x² - 4x - 9 - x² + 2x + 3 to simplify

We first group and find like terms and then add and cancel out

2x²-x²- 4x+2x - 9+ 3

=x²-2x-6

Mickey did not add the coefficients -4 and +2 for x terms in the expression, instead it looked like he added 4+2 as the coefficients

Therefore the correct option is

Mickey should have added –4 and 2 when combining the coefficients of the x terms.

Answer:

Mickey should have added –4 and 2 when combining the coefficients of the x terms.

Answer:

distance travelled by sprinter = 100 m

Time taken = 11.21sec

∵speed = distance/time taken

= 100/9.83

= 10.17 m/s

Now we know, 1 km/h = 1000/3600 m/s

so, 1 m/s = 3600/1000 km/h = 18/5 km/h

∴ 10.17 m/s = 10.17 × 18/5 = 10.17 × 18/5 = 36.612 km/h

Hence, average speed = 36.612 km/h

The correct answer is 26.8328157

Step-by-step explanation:

All you have to do to get this answer is you have to...

Let sqrt (x) - sqrt(y) be the square root.

6 - sqrt(20) = x + y - 2 * sqrt(xy)

So x+y = 6. And x * y = 5.

Clearly x = 5 and y = 1, as we want positive square root.

Answer = sqrt 26.8328157

The answer is D. √120

Step-by-step explanation:

Using the pythangorean theorem when solving the missing side of a right triangle, so given a^2 + b^2 = c^2. We have side c, and a so we must rearanged this to fit side b.

So: a^2 + b^2 = c^2 → b^2 = c^2 - a^2 →

b = √(c^2 - a^2).

Given side c or the hypotenuse is 17, and a is 13. side b must have a length of:

√(17^2-13^2) = √(289 - 169) = √120

The value of the length of EF in the right triangle is,

⇒ EF = √120

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

We have to given that;

In triangle DEF,

DF = 13

DE = 17

Hence, By using Pythagoras theorem,

⇒ DE² = EF² + DF²

⇒ 17² = EF² + 13²

⇒ 289 = EF² + 169

⇒ EF² = 289 - 169

⇒ EF² = 120

⇒ EF = √120

Thus, the length of EF in the right triangle is,

⇒ EF = √120

SECOND QOURDANT

Step-by-step explanation:

The graph lying in first quadrant and graph of horizontal line lying in the fourth quadrant are representing functions.

A function is such type of mapping which strictly has one and only one value corresponding to each input given to the function.

The  graph of first quadrant satisfies the condition of a mapping being a function.

The second quadrant contains a graph of parabola but as it is visible, the graph has two values for each input x it takes from -3 to -6. Example: At x = -6, the function outputs y = 2 and y = 5 two values. Thus it is NOT a function.

The third quadrant contains similar graph which also doesn't satisfy the single output constraint. Example, at x = -1, it outputs y = -2 and y = -6 both. Thus its NOT a function.

The fourth quadrant has a graph of two lines. First line is horizontal and has only one value to each x it allows as valid input.  Thus it represents a function.

In the same fourth quadrant lies another line but that is vertical. For value x=4. it has several values of y. Thus its NOT a function either.

Thus the graph lying in first quadrant and graph of horizontal line lying in the fourth quadrant are representing functions.

Answer:

The diameter of a circle with the equation is 16.

Step-by-step explanation:

Given the equation

[tex]\left(x\:-\:4\right)^2\:+\:\left(y\:+\:6\right)^2=\:64[/tex]

We know that the circle equation with radius 'r', centered at (a, b)

[tex]\left(x-a\right)^2+\left(y-b\right)^2=r^2[/tex]

[tex]\mathrm{Rewrite}\:\left(x-4\right)^2+\left(y+6\right)^2=64\:\mathrm{in\:the\:form\:of\:the\:standard\:circle\:equation}[/tex]

[tex]\left(x-4\right)^2+\left(y-\left(-6\right)\right)^2=8^2[/tex]

Here,

radius = r = 8

center = (4, -6)

Hence, the radius of the circle is: r = 8

we know that

diameter = 2r

               = 2(8)

               = 16

Therefore, the diameter of a circle with the equation is 16.
