5/10 bc it is equal to 1/2 which is bigger than 2/5 or 4/10 1/3
        
             
        
        
        
Using a trigonometric identity, it is found that the values of the cosine and the tangent of the angle are given by:
<h3>What is the trigonometric identity using in this problem?</h3>
The identity that relates the sine squared and the cosine squared of the angle, as follows:

In this problem, we have that the sine is given by:

Hence, applying the identity, the cosine is given as follows:






The tangent is given by the sine divided by the cosine, hence:

Answer: Below
Step-by-step explanation: 
Just mutiply x on both sides which gives you 2x^2 + 12x then you mutiply 2x^2 then subtract that number on both sides and it gives you x = something then you distribute it on 8(something) - 18 you subtract
 
        
                    
             
        
        
        
3(x-8)=12
I got this equation since there are three of the "x-8" sections that add up to the twelve length bar above
        
             
        
        
        
Answer:
28.4 
Step-by-step explanation:
Given that:
Mean, m = 31.3
Standard deviation, s = 2.8
Since, data is normally distributed :
P(x < 0.15) gives a Z value of - 1.036
Using the Zscore formula :
Z = (x - mean) / standard deviation
-1.036 = (x - 31.3) / 2.8
-1.036 * 2.8 = x - 31.3
-2.9008 = x - 31.3
-2.9008 + 31.3 = x 
28.3992 = x 
The temperature which correlates to the bottom 15% of the distribution is 28.4
