Answer:
67.97
Step-by-step explanation:
let AC be length of ladder and BC be distance between ladder and wall and angle be theta
Now,
costheta=BC/AC
THETA =COS^-1(3÷8)
THETA=COS^-1(0.375)
THETA=67.97 DEGREE
 
        
             
        
        
        
Area formula of a parallelogram is
        A = base x height
Given are the
Area = 60 m² and base = 10 m
 Substitute the given:
60 = 10h  (divide by 10 to find value of h)

  (10 and 10 cancels out)
h = 6The 
height of a parallelogram with a base of 10m and an area of 60m² is 
6m
