Answer:
1: 5.83
2: 4.12
3: 3.61
4: 5
5: 6.32
6: 5.10
Step-by-step explanation:
The Pythagorean theorem is a^2 + b^2 = c^2
For all of these you can count the number of blocks over to find two sides of the triangle. 
For example: the first one has two sides, one is 3 units, the other is 5. To find the missing angle you square 3 and 5, then add that together. That is equal to 34. 34 = c^2. To get the c by itself, you then take the square root of 34. So the missing side (c) is equal to 5.83. 
 
        
             
        
        
        
That is not possible, since 20 has the factors of 1,2,4,5,10, and 20. None of those add up to 17, maybe your question has a mistake in it. For further questions, you can message me. Hope this helps! Please rate brainiest answer.
        
             
        
        
        
Answer:
Step-by-step explanation:
P = $ 500 ;r =8% ;  n= 8
A = P* (1+r/100)^n
A= 500 * ( 1 + 8/100)⁸
 = 500 * ( 1 + 0.08)⁸  = 500 * 1.08⁸
=500*1.85
= $ 925.45
 
        
             
        
        
        
Yes, there is a type of triangle called a "3 4 5 triangle" with side lengths 3, 4, and 5.
