Answer:
Step-by-step explanation:
<u>Given:</u>
- Cost price = $16.50
- Mark up rate = 120%
<u>Selling price is:</u>
- $16.50 + 120% = 
- $16.50*2.2 = 
- $36.30
 
        
             
        
        
        
They said start with x so x is 90° then the others can be 90° but may hav other angles
        
             
        
        
        
I think the answers are: a = 60°, b = 45°, c = 36°.
        
             
        
        
        
It is 80 !!!!!!! That’s the number
