Step-by-step explanation:

They are adjacent angles.

Adjacent angles are right next to each, or side-by-side. Considered (by my math teacher) the next door neighbors.

Answer:

They are supplementary!

Explanation:

Not sure if this is the type of relationship you're after, but angles that add up to a flat line (or, 180 degrees) are known as supplementary.

Find the distance of the line segment joining the two points (-4 /2 - /12) and (/32, 2/3)

astraxan [27]

Answer: $4\sqrt{3}$ .

Step-by-step explanation:

Distance formula : Distance between points (a,b) and (c,d) is given by :-

$D=\sqrt{(d-b)^2+(b-a)^2}$

Distance between points $(-4\sqrt{2},\sqrt{12}) \text{ and }(-\sqrt{32}, 2\sqrt{3})$ .

$D=\sqrt{(2\sqrt{3}-(-\sqrt{12}))^2+(-\sqrt{32}-(-4\sqrt{2}))}\\\\=\sqrt{(2\sqrt{3}+\sqrt{2\times2\times3})^2+(-\sqrt{4\times4\times2}+4\sqrt{2})^2}\\\\=\sqrt{(2\sqrt{3}-\sqrt{2^2\times3})^2+(-\sqrt{4^2\times2}+4\sqrt{2})^2}\\\\=\sqrt{(2\sqrt{3}+2\sqrt{3})^2+(-4\sqrt{2}+4\sqrt{2})^2}\\\\=\sqrt{(4\sqrt{3})^2+0}\\\\=4\sqrt{3}\text{ units}$

Hence, the correct option is $4\sqrt{3}$ .

Can someone please help!

Answer:

The value of x is 49 and the value of AB is 90

Step-by-step explanation:

You know that AB and DE are congruent. That information is given to you.

You set the equations equal to each other and then solve.

2x - 8 = x + 38

Subtract x

x - 8 = 38

Add 8.

x = 49

Plug back into 2x - 8 to find the value of AB

2 times 49 - 8

98 - 8
