Answer: 90° 
Explanation: the sum of all the angles in a triangle = 180. So 70 + 30 = 90 and 180-90=90
        
             
        
        
        
-5, you never want the denominator to equal zero or else it doesnt exist!
x+5=0
x=-5
        
             
        
        
        
First you convert 20% into a decimal which is 0.2 and multiply that by 42 and you get 8.4, that's the discount. Then you subtract 8.4 from 42 and get $33.60 which is your answer. Hope this helps!!
        
                    
             
        
        
        
Answer:
67 degrees
Step-by-step explanation:
All angles in a triangle add up to 180 degrees. So...
23 + x + 90 = 180
113 + x = 180
x = 67 degrees
