Both procedures are correct. Because the end answer and the step-by-step explanation are right.

<h3>What is the procedure?</h3>

It is a step-by-step explanation of the equations. The procedure is important

It explains the sequence of actions and specifies what has to be done at each stage, frequently specifying when and by whom the procedure should be conducted.

The end answer for Keisha's solution is;

$\rm cos \theta =$ ± $\frac{15}{17}$

The end answer for David's solution is;

$\rm cos \theta =$ ± $\frac{15}{17}$

Hence both procedures are correct. Because the end answer and the step-by-step explanation are right.

Prove that the segments joining the midpoint of consecutive sides of an isosceles trapezoid form a rhombus.

Stella [2.4K]

Answer:

B. See explanation

Step-by-step explanation:

Use the distance formula between two points $(x_1,y_1)$ and $(x_2,y_2):$

$d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$

Find the lengths of all sides of quadrilateral DEFG:

$DE=\sqrt{(-a-b-0)^2+(c-2c)^2}=\sqrt{(a+b)^2+c^2}\\ \\EF=\sqrt{(a+-b-0)^2+(c-2c)^2}=\sqrt{(a+b)^2+c^2}\\ \\FG=\sqrt{(a+b-0)^2+(c-0)^2}=\sqrt{(a+b)^2+c^2}\\ \\GD=\sqrt{(-a-b-0)^2+(c-0)^2}=\sqrt{(a+b)^2+c^2}\\ \\$

All sides are of the same length. Now fond the slopes of all sides:

$DE=\dfrac{2c-c}{0-(-a-b)}=\dfrac{c}{a+b}\\ \\EF=\dfrac{c-2c}{a+b-0}=-\dfrac{c}{a+b}\\ \\FG=\dfrac{c-0}{a+b-0}=\dfrac{c}{a+b}\\ \\GD=\dfrac{c-c}{-a-b-0}=-\dfrac{c}{a+b}\\ \\$

The slopes of the sides DE and FG are the same, so these sides are parallel. The slopes of the sides EF and GD are the same, so these sides are parallel.
