Answer:
148°
Step-by-step explanation:
it is very close to the 150 line and the option closest to 150 is 148
 
        
                    
             
        
        
        
For this case we must find the quotient of the following expression:

By definition of power properties we have:

Rewriting the expression we have:

By definition of multiplication of powers of the same base we have to put the same base and add the exponents:

Answer:
i believe its 12.56637 but rounded off that will be 12.57 
 
        
             
        
        
        
Following the principle of supplements angles, the angle next to the 101 is 79°. 79+38+c(call the third angle c) = 180
c = 180-117 =63° x is supplemental to c so 180 = x +c 
180=x + 63 
x =117
