Answer:
Step-by-step explanation:
<u>Use cosine:</u>
- cos = adjacent / hypotenuse
- cos ∠L = KL/JL
- cos 21° = 4/x
- x = 4 / cos 21°
- x = 4.3 (rounded)
 
        
                    
             
        
        
        
That's an awfully broad question.  Could you not be more specific?
A basic example:  Suppose you are told that sin theta = 1/2.  Solving this equation would require finding the measure of the angle theta.  In this case the answer would be "30 degrees," or "pi/6 radians."
        
             
        
        
        
Question 7: 40. 40 is way above the other data.
Question 8: Median is 7, and the range is 12, the difference is 5.
Question 9: The first mean was 6, and it went up to 6.75. There is a 0.75 difference.
Question 10: The range increases by one.
        
             
        
        
        
(3^6 / 3^5)^2 = (3^(6 - 5))^2 = (3^1)^2 = 3^2 = 9
        
             
        
        
        
Answer: y= -7
Step-by-step explanation:
Zero slope are horizontal lines. Horizontal lines have the equation Y= a number. That number is the y value of the point.
