Answer:

See attachment for triangle

Step-by-step explanation:

Given

Shape: Equilateral triangle

$Perimeter = 10cm$

Required

Draw the triangle

First, we determine the side lengths.

The perimeter of an equilateral triangle is:

$Perimeter = 3 * Length$

So, we have:

$10= 3 * Length$

Solve for Length

$Length = \frac{10}{3}$

$Length = 3.33$

katrin2010 [14]

Answer and Step-by-step explanation:

1. slope intercept

2. point-slope form

3. standard

Explanation:

m = slope

b = y-intercept

2. A point-slope form is when a line passes through a point

and the equation is set up as y −b = m ( x−a)

m = slope

(a, b) A point that the line passes through

3. standard lope form is when the equation is set up as
