Answer:

x = 20

Step-by-step explanation:

This is an equilateral triangle since all of the sides are the same.

So each angle has to be 60 degrees since a triangle is 180 degrees total.

3x = 60

60 divided by 3 = 20

So the value of x is 20.

Hope it helped! My answer is expert verified.

Answer:

x = 20

Step-by-step explanation:

Since all given side lengths are equal then the angles also must be equal therefore this triangle is an equilateral triangle and each angle has a measurement of 60°

3x = 60° divide both sides by 3

x = 20

The length of a rectangle is 3 cm less than twice the width. If the perimeter is 42 cm, what is the length of the rectangle?
larisa [96]

Answer:

The length is 13

Step-by-step explanation:

w+w+l+l= perimeter

if the length is 3m less than twice the width then let's do some math.

42 divided 2 =21. so the width and length of one side have to equal 21. For example, let's use 8 as the width. The length would be twice(16) minus three(13) 13 plus 8 is 21. WOW it equals half of it so no we know the length is 13 and the wdith is 8.

Which value is a solution of the equation 2 - 8x = -6?<br> A. 1<br> B. 1/2<br> C. -1<br> D. 8
Nuetrik [128]

Answer:

A.) 1

Step-by-step explanation:

First change the equation to 2 + ( - 8x ) = -6 so it’s easier to read

Take away 2 from both sides

So now you have -8x = -8

Divide both sides by -8 so you get positive x and 1

x = 1
