Answer:
31.7 cm²
Step-by-step explanation:
The area (A) of the triangle is calculated as
A =  absinC
 absinC
where a, b are the 2 sides given and C the angle between them
∠ C = 180° - (72 + 59)° = 180° - 131° = 49° , thus
A = 0.5 × 12 × 7 × sin49° ≈ 31.7 cm² ( to 1 dec. place )
 
        
             
        
        
        
The answer is 3 because z to the y a-1
        
                    
             
        
        
        
True they are equivalent fractions both are divided by -3 to get 14/15
