Answer:
Step-by-step explanation:
Let yesterday's price  be x
Discount percentage = 36%
Sale price = $ 560
(100-36)% of x = 560
64 % *x = 560

Yesterday's price = $ 875
 
        
             
        
        
        
X axis : -t1 cos 60 + t2 cos 60 = 0
 
            t2 cos 60   = t1 cos 60    ; t2   = t1
Y axis : t1 sin 60  + t2 sin 60 - 150 = 0
since t2 = t1
2t1 sin 60 =  150
t1 ( sqrt(3)/2)  = 150/2
t1   = 50 [sqrt(3)]
t2 = 50 [sqrt(3)]
t3 = 150 N
hope this helps
        
                    
             
        
        
        
To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together. Be sure than none of the simpler figures have overlapping areas
 
        
                    
             
        
        
        
Y = - 20x + 100
Slope is -20, y-intercept is 100.
