It can be deduced that the triangles are similar because the three internal angles are equal for both triangles.
<h3>How to solve the triangle?</h3>
It should be noted that the triangles are similar because the three internal angles are equal. 
In this case, the ratio of the corresponding sides are equal and the corresponding angles are congruent. 
The width of the river will be:
300/80 = AB/50
AB = (300 × 50)/80
AB = 187.50 feet.

Answer:
The function represents a direct variation
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form  or
 or 
In a linear direct variation the line passes through the origin and the constant of proportionality k is equal to the slope m
Let
 ------> the line passes through the origin
 ------> the line passes through the origin 

Find the value of k------> substitute the value of x and y
 ----->
-----> 

Find the value of k------> substitute the value of x and y
 ----->
-----> 

Find the value of k------> substitute the value of x and y

-----> 

Find the value of k------> substitute the value of x and y
 ----->
-----> 
The value of k is equal in all the points of the table and the line passes through the origin
therefore
The function represents a direct variation
the equation of the direct variation is equal to

 
        
                    
             
        
        
        
I'm not sure what you mean, but if you mean 15 and 1/20th, you just multiply 15 by 20 and add one which is 301 and keep the denominator
        
             
        
        
        
Answer:
A 
Step-by-step explanation:
If it’s 80 less than, your subtracting and then 4 times a number is 4x so your answer is 4x-80
