Answer:

third option

Step-by-step explanation:

<u>angle 1</u>

measure of angle 1 is diagonal to 45, theyre congruent angles

so measure of angle 1 is 45

<u>angle 2</u>

the sum of a triangle is 180 degrees

so for measure 2, we add 45 + 59 and we get 104. then we do 180 - 104 and we get 76

so the measure of angle 2 is 76

<u>angle 3</u>

since we know that the measure for angle 1 is 45, we can also solve for the measure of angle 3

to find angle 3, we do 55 + 45 and we get 100

and then you do 180 - 100 and you get 80

so the measure of angle 3 is 80

Suppose the diameter of a circle is 6 units What is its circumference?

Kipish [7]

Answer:

18.84 estimated, 6π exactly

Step-by-step explanation:

Hi!

<u>The formula for finding the circumference of a circle is 2πr:</u>

In that case, all we need to do <em>first </em>is to divide the diameter by 2, so we can substitute that into the equation.

6 ÷ 2 = 3

So we have 2π × 3 to solve.

2π × 3 = 6π

We can estimate the circumference by multiplying by 3.14.

6 × 3.14 = 18.84

(actually multiplying by π gives 18.849... which is pretty close!)

Thus, the circumference is $\boxed{6\pi{\text{\:or\:18.84\:roughly}}}$ .

Hope this helps!

Of the 58 employees in a firm, 8 are considered support staff, and 7 of the employees have more than five years of experience. A

polet [3.4K]

Using statistical concepts, it is found that the number of outcomes that are possible for the complement of the union of Events J and K is of 43.

<h3>What is the union of events J and K?</h3>

It means that at least one of event J or event K is true, hence, it is composed by employees that are either considered support staff(less than 5 years of experience) or employees that have more than five years of experience, combining a total of 7 + 8 = 15 employees.

<h3>What is the complement?</h3>

The total number of outcomes of the union of J and K, plus the complement, add to the total number of 58, hence:

15 + x = 58

x = 43.

The number of outcomes that are possible for the complement of the union of Events J and K is of 43.
