Step-by-step explanation:

To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides.

...

Here is what it will look like:

area = 1/2 x 120 x 10√3.

area = 60 x 10√3.

What is the slope of the line parallel to the line y = -5/3x + 5?

Aleksandr-060686 [28]

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - $\frac{5}{3}$ x + 5 ← is in slope- intercept form

with slope m = - $\frac{5}{3}$

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular }$ = - $\frac{1}{m}$ = - $\frac{1}{-\frac{5}{3} }$ = $\frac{3}{5}$

Yuliya22 [10]

Answer:

Step-by-step explanation:

vector e is (-1,5),f is (3,-4),g is (2,1)

2i+j=x(-i+5j)+y(3i-4j)

2=-x+3y (multiply by 5)

10=-5x+15y

1=5x-4y

add

11=11y

y=1

2=-x+3(1)

x=3-2=1

2i+j=1(-i+5j)+1(3i-4j)
