A triangle has 3 sides, the total interior angels sum to 180 degrees.
A square has 4 sides, the total interior angels sum to 360 degrees.
A pentagon has 5 sides, the total interior angels sum to 540 degrees.
Do you see a trend?
Answer:
The (s) sum of interior angles equals the (n) number of sides, minus 2, times 180.
This is written as
s = (n - 2) * 180

If we put in 900 for s, we get
900 = (n - 2) * 180

5 = n - 2
n = 7
A polygon with 7 sides is called a Heptagon.

0xBED into 3-base representation

Makovka662 [10]

0xBED is an hexadecimal representation.
Transforming to decimal first:
B => 11
E => 14
D => 13
 $11\times16^2+14\times16+13=3053$
Now by successive devisions, we get the base three:
 $3053=2+2\times3^3+3^4+3^6+3^7$
And the resulting base three expression:
 $11012002_{3}$

Identify the point from the equation: y + 5 = 3(x - 2)

Mice21 [21]

Answer:

The point is $(2,-5)$

Step-by-step explanation:

we have

$y+5=3(x-2)$

This is the equation of the line written in point slope form

$y-y1=m(x-x1)$

where

The slope is equal to

$m=3$

The point (x1,y1) is

$(2,-5)$

therefore

The point is $(2,-5)$
