3/7, 3/5, 1/2 is the answer it starts from the lowest to the lagest
        
             
        
        
        
In 22, you're looking for the vertical height of the triangle. You're given the angle opposite the side you want to find (which I'll call 

) and the length of the hypotenuse. This sets you up with the relation

In 23, you're given a similar situation, except now you're looking for the angle (I'll call it 

) in the triangle opposite the side denoting the height of the airplane. So this time,
 
 
        
        
        
Substitute the value of the variable into the expression and simplify 37
        
                    
             
        
        
        
<span>the product of a number and the same number less 3 
x(x – 3)</span>
The words "the product of" tell us we're going to multiply a number times the number less 3. In this case, we'll use parentheses to represent the multiplication. The words "less 3" tell us to subtract three from the unknown number.
a number divided by the same number less five
The words "divided by" tell us we're going to divide a number by the difference of the number and 5. In this case, we'll use a fraction to represent the division. The words "less 5" tell us we need a minus sign because we're going to subtract five.
