Answer:
28 m
Step-by-step explanation:
The top angle in the triangle = 90° - 62° = 28°
Using the cosine ratio in the right triangle
cos28° =  =
 = 
cross- multiply
x × cos28° = 25 ( divide both sides by cos28° )
x =  = 28.31425... ≈ 28 m
 = 28.31425... ≈ 28 m
Thus the distance from the top to the crocodile is 28 m
 
        
                    
             
        
        
        
Answer:
 (2•5y to the 7th power)
Step-by-step explanation:
Step 1:  (2y to the 4th power • 5) • y to the 3rd power
Step 2:  (2•5y to the 4th power) • y to the 3rd power
Step 3:  3.1    y to the 4th power multiplied by y to the 3rd power = y to the  (4 + 3) power = y to the 7th power
Final answer:  (2•5y to the 7th power)
