Find the value of x

AveGali [126]

Answer:

x = 120

Step-by-step explanation:

Since they are supplementary, they add up to 180 degrees.

So, you can say x + x/2 = 180

Then, you would solve it like an algebra problem.

Multiply both sides by 2

2x + x = 360

Simplify

3x = 360

Divide both sides by 3

x = 120

Whats the distance between (-8,-7) (8,-4)

balandron [24]

To find the distance between points, use the distance formula.

Distance formula: $\sqrt{ (x_{2} - x_{1})^{2} + ( y_{2} - y_{1})^{2} }$

Plug in your values for $x_{2}, x_{1}, y_{2}, y_{1}$ using (-8, -7) and (8, -4) and solve.

$\sqrt{(8 - (-8))^{2}+(-4 - (-7))^{2}}$
$\sqrt{(8+8)^{2}+(-4+7)^{2}}$
$\sqrt{(16)^{2}+(3)^{2}}$
$\sqrt{256+9}$
$\sqrt{265}$ ≈ $16.28$

Answer:
Approximately 16.28 units.
