Answer:
2.25
Step-by-step explanation:
to find slope it is (y2-y1)/(x2-x1)
(15.25-8.50)/(5-2)
6.75/3
2.25 is the slope
 
        
                    
             
        
        
        
Cos 52 = 0.6157
sin 42 = cos 48 = 2/3     (because 42 + 38 = 90 - complementary angles)
if tan 20,5 = 3/8 then  tan 69.5 wil =  1 / 3/8  = 8/3
