$\bf \textit{sum of exterior angles}\\\\ n\theta =360~~ \begin{cases} n=\textit{number of sides}\\ \theta = \textit{angle in degrees}\\[-0.5em] \hrulefill\\ n=15 \end{cases}\implies 15\theta =360 \\\\\\ \theta =\cfrac{360}{15}\implies \theta =24$

What is the distance between (10, 6) and (-2, -3)

Helga [31]

Answer:

15 units.

Step-by-step explanation:

The distance between the points (x1, y1) and (x2, y2) is

√(x1-y1)^2 + (y1-y2)^2))

So here it is:

√(10- -2)^2 + (6- -3)^2)

= √(144+81)

= √225

= 15.

18 divide by 2 * 3/5-2 simplify show all work

liraira [26]

Answer:

Step-by-step explanation:

I would guess it looks like this - if not then tell me

$\frac{18}{ \frac{2 \times 3}{5 - 2} }$

2×3=6

5-2=3

Then there's only

$\frac{18}{ \frac{6}{3} }$

Which is equal to

$\frac{18}{1} \times \frac{3}{6} = \frac{54}{6} = \frac{9}{1} = 9$
