Answer:
A
Step-by-step explanation:
First you do distributive property.
2c + 8 = 0
Then subtract 8 with 0
2c = -8
Then divide -8/2
<h2>c = -4</h2><h2>Hope this helps :)</h2><h2 />
Answer:
The correct option is
Option d. Sin θ = -√65/9 and Tan θ = -√65/4
Step-by-step explanation:
Points to remeber
Sin θ = Opposit side/ Hypotenuse
Cos θ = Adjacent side/Hypotenuse
Tan θ= Opposite side /Adjacent side
<u>To find opposite side</u>
It is given that,
Cos θ = -4/9 = Adjacent side/Hypotenuse
We can find opposite side of angle θ
opposit side ² = Hypotenuse² - adjacent side² = 9² - 4²
= 81 - 16 = 65
Opposite side = √65
<u>To find sinθ and tanθ</u>
Sin θ = Opposit side/ Hypotenuse = -√65/9
Tan θ = Opposite side /Adjacent side = -√65/4
Therefore the correct option is
Option d. Sin θ = -√65/9 and Tan θ = -√65/4

1) To find y, you should use the pythagorean theorem
30^2 = 24^2 + y^2
So y = 18
Hello there!
An outlier is a number that is far away from the others. In this data set, all the numbers are between 47 and 54 EXCEPT for 4.
Find the difference between the greatest number: 54
54 - 53 = 1
54 - 49 = 5
54 - 48 = 6
54 - 47 = 7
54 - 4 = 50
The greatest differene is between 54 and 4. Therefore, the outlier is 4 because it is far from the other numbers.
