Answer:
the first one
Step-by-step explanation:
Hey There!
Look at the image for the rule of a 30- 60 - 90 triangle 
x = 5
the hypotenuse would be x2 so 10 
the longer leg would be x
So the first triangle is the right answer 
 
        
             
        
        
        
First, find the scale factor. 
8.4 / 7 = 1.2
9 / 7.5 = 1.2
7.2 / 6 = 1.2
Since both solids are different sizes, the solids aren't congruent. 
The size ratio for all the sides are:
8.4:7
9:7.5
7.2:6
Since the scale factor isn't 1:1 this also proves that the solids are NOT congruent. 
Since both solids are the same kind of shape and have an identical scale factor, the solids are similar.
Best of Luck!

Step-by-step explanation:
Synthetic division is useful for finding the quotient. Or, you can use polynomial long division. The result is the same, but synthetic division requires less writing.
