Step-by-step explanation:

Charlie made the mistake by not getting the equation equal to zero.

$x^2 - 9x + 8 = 16$

Subtract 16 to both sides making it equal to 0.

$x^2 - 9x - 8 = 0$

Callie solved this one-variable equation. When she was done, she tried to verify her answer, but found that it was wrong. Can yo

Andrews [41]

2(4k+8)=10
8k+16=10 (she said 2k instead of 8k)

To continue solving, subtract 16 from both sides. That would give you 8k= -6. Then divide both sides by 8, and get -6/8 which equals -3/4.

If triangle ABC is similar to triangle DEC, find the values of x and y.

Mumz [18]

The values are x=8 and y=35, if the given ΔABC and ΔDEC are equal, it is obtained by Pythagoras theorem.

Step-by-step explanation:

The given are,

From ΔABC,

AB= 6

BC= 10

AC = x

From ΔDEC,

CD= 28

DE= 21

CE = y

Step:1

Pythagoras theorem from ΔABC,

$BC^{2}=AB^{2} + AC^{2}$ ...............(1)

Substitute the values,

$10^{2}$ = $6^{2}$ + $AC^{2}$

100 = 36 + $AC^{2}$

$AC^{2}$ = 100 - 36

= 64

AC = $\sqrt{64}$

AC = 8

AC = x = 8

Step:2

Pythagoras theorem for ΔDEC,

$CE^{2} = CD^{2} + DE^{2}$ ................(2)

From the values,

$CE^{2}$ = $28^{2}$ + $21^{2}$

$CE^{2}$ = 784 + 441

= 1225

CE = $\sqrt{1225}$

CE = 35

CE = y = 35

Result:

The values are x=8 and y=35, if the given ΔABC and ΔDEC are equal.

AC and BD intersect at point E which is inside the circle. Find the measure of Arc AB if Arc CD = 60 degrees and Angle CED = 35

tia_tia [17]

Th measure of arc AB will be 60 degrees

<h3>Circle theorem</h3>

The figure shown shows a circle with lines AC and BD intersecting the circle at the point E

From the figure given the measure of the arc AB is congruent to the arc CD.Given that the measure of arc CD is 60 degrees, hence the measure of arc AB will also be 60 degrees
