Answer:
74
Step-by-step explanation:
2x+x+4=115 (ext ∠)
3x=111
x=37
∠MNO=2(37)
            =74°
 
        
                    
             
        
        
        
256.
EXPLANATION:
When you are using exponents, you are basically just doing repeated multiplication.
Whatever the exponent (smaller number is) is how many times you multiply the base number by itself.
So 4 ^4 is 4 x 4 x 4 x 4. (4 fours.)
So 4 x 4 x 4 x 4 is 256.
