Answer: x= 5.3
Step-by-step explanation:
Looking for side opposite and adjacent so we use tangent or tan. The equation is Tan(angle) = opposite/adjacent so input the numbers... Tan24=x/12 and to solve for x(missing side) multiply both sides by 12 to cancel out and get 5.3427 rounded is 5.3
 
        
             
        
        
        
The answer is 150. 
(5)^2(9-3)
25(6)
=150
