We are given three angle values, all which have the variable x in them. All three of these angles happen to be suplementary, or add to 180. So we can write a formula where we set the sum of all three angles equal to 180 and solve for x.

(6x+2)+(8x+6)+(7x+4)=180 (combine like terms)
21x+12=180 (subtract 12 from both sides)
21x=168 (divide both sides by 21)
X=8

Hope this helps

Since angles EFA, AFB, and BFC lie on a straight line, then they must add up to 180° (angle sum of a straight line)

So, 7x + 4 + 8x + 6 + 6x + 2 = 180
21x + 12 = 180
21x = 168
x = 8

A triangle has two sides that measure 4ft and 3ft. Which could be the measure of the third side?
Nezavi [6.7K]
The measure of the third side must be less than the sum of the other two. That property is valid for all triangles.

For this question, call x the measure of the third side. So you must have

x < 4 + 3

x < 7 ft

The only option that satisfies the condition above is

option A) 5 ft.

I hope this helps. =)

Plz help!! A jar contained 6 red marbles, 10 green marbles, and 8 blue marbles. A marble was selected at random, the color was r
Inessa [10]

Answer:

To calculate the relative frequency, first we need to know what exactly is and how to calculate it.

Relative frequency is the ratio between the absolute frequency (how many repetitions have a specific outcome) and the total outcomes. Also, this type of frequency is used to show the representation that some data have over the whole distribution.

So, in this case, we need to just divide 13, which belongs to red marble's results, to 60 which is the total outcomes, as it's presented:

         13redmarble                                                                                                                       Fr = -------------------------

       60 totalmarbles  

Normally, relative frequency is shown as a percentage multiplying this result by 100. Therefore, 22% is the approximate percentage of the relative frequency, which means that 22% is the representation of red marbles outcomes of the whole distribution, or we can say it as a probability: there's 22% of chances when someone extract a marble, it will be red.
