Answer:

<h2>ABC ≅ EDC, because m∠3 = m∠4 and m∠1 = m∠5</h2>

Step-by-step explanation:

The two triangles are congruent because they both consist of alternate interior and vertical angles.

m∠3 and m∠4 are vertical angles, because they are right on top of each other. Also because one angle is one one side of the transversals, and the other angle is on the other side.

m∠1 and m∠5 are alternate interior angles, because each angle is on each side of both transversals, and they both are congruent.

The change in altitude of a bird after 2 __ 1 2 seconds was –41 __ 1 4 feet. What was the average change in altitude of the bird

svlad2 [7]

Answer:

$Average\ Change = -1\frac{7}{10} ft/s$

Step-by-step explanation:

Given

$Altitude\ Change = -4\frac{1}{4} \ ft$

$Time = 2\frac{1}{2}\ s$

Required

Determine the average change

This is calculated as follows:

$Average\ Change = \frac{Altitude\ Change}{Time}$

This gives:

$Average\ Change = \frac{-4\frac{1}{4}}{2\frac{1}{2}}$

$Average\ Change = -4\frac{1}{4}/2\frac{1}{2}$

Convert to improper fractions

$Average\ Change = -\frac{17}{4}/\frac{5}{2}$

Convert to multiplication

$Average\ Change = -\frac{17}{4}*\frac{2}{5}$

$Average\ Change = -\frac{17}{2}*\frac{1}{5}$

$Average\ Change = -\frac{17}{10}$

$Average\ Change = -1\frac{7}{10} ft/s$

For the figure above: Assume that <ABD has a mesure of 105° ANSWER ASAP WILL GIVE 15 POINTS AND BRAINLIEST

kykrilka [37]

Answer:

DBC = 75

Step-by-step explanation:

ABD and DBC are supplementary angles. They add to 180 degrees.

ABD + DBC = 180

105 + DBC = 180

Subtract 105 from each side

105-105 + DBC = 180-105

DBC = 75

Answer:

The slope of the line is -1

Step-by-step explanation:

Slope of a Line

Suppose we know a given line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated as follows:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

From the table in the image, we select the points (1,4) (3,2). The slope is:

$\displaystyle m=\frac{2-4}{3-1}=\frac{-2}{2}=-1$

Now select two other points like (5,0) (7,-2)

$\displaystyle m=\frac{-2-0}{7-5}=\frac{-2}{2}=-1$

Following the same procedure with any other pair of points, we'll get the very same result:

The slope of the line is -1
