<u><em>Answer:</em></u>sin (C)
<u><em>Explanation:</em></u><u>In a right-angled triangle, special trig functions can be applied. These functions are as follows:</u>
sin (theta) = </span>

<span>
cos (theta) = </span>

<span>
tan (theta) = </span>

<span>
<u>Now, let's check the triangle we have:</u>
<u>We have two options:</u>
<u>First option:</u>5 is the hypotenuse of the triangle
4 is the side adjacent to angle B
Therefore, we can apply the <u>cos function</u>:
cos (B) = </span>

<span>
<u>Second option:</u>5 is the hypotenuse of the triangle
4 is the side opposite to angle C
Therefore, we can apply the <u>sin function</u>:
sin (C) = </span>

<span>
Among the two options, the second one is the one found in the choices. Therefore, it will be the correct one.
Hope this helps :)

Answer : 
(1) 
Use FOIL method to mulitply (3x – 5)(3x – 5)

(2) 
Use FOIL method to mulitply (3x - 5)(3x + 5)

(3) 
Use FOIL method to mulitply -(3x + 5)(3x + 5)

(4) 
Use FOIL method to mulitply -(3x + 5)(3x - 5)

So equation 2 is true
Answer: The slope of the line is 2.
Step-by-step explanation:
Slope = change in y/change in x
Slope = (8-4)/(4-2)
Slope = (4)/(2)
Slope = 2
