PLEASE HELP

1 answer:

Anna007 [38]2 years ago

Answer:

She used the AA theorem because the two interior angles B and D are equal to 85 degrees. ABC and EDC are equal because they are vertically opposite angles.

ABC=EDC

ABC~EDC By AA criterion of similarity

AB/ED = AC/EC Because the corresponding sides of similar triangles are proportional.
Suppose (DE) =105 ft. Calculate the distance of (AB) . Show your work. Don’t forget to label your answer.

The answer is AB= 903

105=DE 25=DC 215=CB 903=AB

105/25= 4.2

4.2 * 215 = AB=903

Answer:

-3=k y=24

Step-by-step explanation:

y=kx.

-18=k(6)

k=-3.

So our value of k is -3 now, let solve for y.

y=kx

y=(-3)(-8)

y=24

Review the graph.

lisabon 2012 [21]

Answer: A, Magnitude of 8 and direction angle equal to 0°

Step-by-step explanation:

Since vector u is only a straight line, there will be no angle, which means that answers B and D are automatically wrong.

Now, we’re going to use the distance formula to find the component form of vector u

$\sqrt{(6-(-2)^2+(3-3)^2}\\\\\sqrt{(8)^2+(0)^2}$

Now we found the new coordinate, which is (8,0), and it is being extended from the origin with the same angle of 0°

Using the formula from above, we can find the magnitude of vector u

$\sqrt{(8)^2+(0)^2} \\\\\sqrt{64+0}\\\\\sqrt{64}\\\\8$

Hope I explained it well and hopefully this helps!

What is the slope of the line.

uranmaximum [27]

Step-by-step explanation:

Two points on the line are (1,4) and(-4,-4)

slope of the line =

$\frac{ y2 - y1}{x2 - x1}$

$\frac{ - 4 - 4}{ - 4 - 1}$

$\frac{ - 8}{ - 5}$

$\frac{8}{5}$
