Answer:
These triangles cannot be proved congruent
Step-by-step explanation:
The theorems for congruence are  SSS SAS ASA AAS. Here, there is only one common side and one common angle marked, therefore you cannot prove congruency.
 
        
                    
             
        
        
        
Answer:
65%
Step-by-step explanation:
STEP ONE:
Find unit percent of 40. You should get 0.4.
STEP TWO:
Divide 26 by 0.4 and get 65.
So, the answer is 65%.
 
        
                    
             
        
        
        
Answer:
4.80 mm to 2 d.p
Step-by-step explanation:
w = f(r)
f'(r) = (dw/dr) = (0.0218 mm/mm)
So, for a small difference in rainfall of 220 mm, what is the corresponding small difference in width of leaves in the two forests given.
One definition of a derivative or a rate of change is that it is the ratio of very small differences in the dependent variable to very small differences in the independent variable.
Mathematically,
(dw/dr) = (Δw/Δr) for very small Δw and Δr.
0.0218 = (Δw/220)
Δw = 0.0218 × 220 = 4.796 mm = 4.80 mm to 2 d.p
Hope this Helps!!!
