If secant of theta =

<span>
1.0416666667

then
theta = 16.26 Degrees
cotangent of theta = 3.4286
        
                    
             
        
        
        
<span>
-4c - 11 = 4c +21                                        add 4c to both sides
</span>
<span>
-4c - 11 + 4c = 4c + 21 + 4c                        simplify
- 11 = 8c + 21</span>                                <span>               subtract 21 from both sides
- 11 - 21 = 8c + 21 - 21                                </span><span>simplify
- 32 = 8c                                                      divide both sides by 8
c = - 4That's it

Answer:
115°
Step-by-step explanation:
Knowing that the sum of all interior angles of any triangle is 180 degrees, we can find the measurement of the missing angle of the triangle. The calculation is 180 - 75 - 40 = 65. Then, notice that the blue angle and the missing angle are supplementary (linear; add up to 180 degrees). So we can find the blue angle's measurement by 180 - 65, so the answer is 115 degrees.
 
        
             
        
        
        
Exponential. 
One way to think about this, is to ask how much you will lose each year. The first year you're losing 20% of $20,000 ($4,000). The second year you're losing 20% of 16,000 ($3,200). The dollar value your car loses each year diminishes exponentially, so it is not a linear but an exponential function.
