ValentinkaMS [17]

Answer:

b. 44°

Step-by-step explanation:

Reference angle = x

Hypotenuse = 21

Adjacent = 15

Apply trigonometric function CAH:

$Cos(x) = \frac{Adj}{Hyp}$

$Cos(x) = \frac{15}{21}$

$x = cos^{-1}(\frac{15}{21})$

x = 44.4153086° ≈ 44° (nearest degree)

Hello I need help on this math question

Zigmanuir [339]

Answer:

$50.24\ cm ^2$

Step-by-step explanation:

Let's start by finding the radius of this circle.

$D=2r\\8=2r\\\text{Divide both sides by 2}\\r=4$

Note that in the equation:

$A=\pi r^2$

"A" stands for area and "r" stands for radius.

Now, let's substitute the given values into the equation.

$A=\pi r^2\\A=3.14*(4)^2\\A=3.14*16\\A=50.24\ cm^2$

If 75 percent of the employees of a certain company take a winter vacation, 40 percent take a winter and a summer vacation, and

KATRIN_1 [288]

Answer:

The answer is option A : 5%

Step-by-step explanation:

We have the following information in percentage:

Employees taking winter vacation= 75

Employees taking both winter and summer vacation= 40

Employees taking none vacation = 20

We can assume the situation as following:

Winter + Summer - Both + Neither = 100

We get;

75 + Summer - 40 + 20 = 100

So, summer = 45

45 people take vacations in summer. But 40 of them take vacation in winters too.

So, people taking vacations in summer but not winter means summer only.

This is : $45-40=5$ %

Therefore, the answer is option A : 5%
