Answer:
angle 3 is 140°
Step-by-step explanation:
angle 2 and angle 3 are equal
angle 4 and 1 are also equal
angle 3 = 
180-40= 140
angle 3 is 140
 
        
                    
             
        
        
        
The value of x is 1/13 (4th choice) 
Step-by-step explanation:
![{a}^{ \frac{m}{n} }  =  \sqrt[n]{ {a}^{m} }](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B%20%5Cfrac%7Bm%7D%7Bn%7D%20%7D%20%20%3D%20%20%5Csqrt%5Bn%5D%7B%20%7Ba%7D%5E%7Bm%7D%20%7D%20)
If 14^x = ¹³√14, what value of <em>x </em>makes this equation true? 
![\sqrt[13]{14}  =  {14}^{x}  \\  \sqrt[13]{14}  =  {14}^{ \frac{1}{13} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B13%5D%7B14%7D%20%20%3D%20%20%7B14%7D%5E%7Bx%7D%20%20%5C%5C%20%20%5Csqrt%5B13%5D%7B14%7D%20%20%3D%20%20%7B14%7D%5E%7B%20%5Cfrac%7B1%7D%7B13%7D%20%7D%20)
So, the value of <em>x</em> is 1/13 (4th choice)
