Did you get this answer???!
        
                    
             
        
        
        
Answer:
I want to show you how to do this as well, the formula you are working with is a^2+b^2=c^2
Step-by-step explanation:
1.) 8^2+b^2=12^2
 64+b^2=144
subtract 64 from both sides
 b^2=80
take the square root of 80 and you get 
 b= 8.9
if you need more help on this let me know, I am going to list the other answers now because to do it all and show work on here is a lot of typing, all of which I will do if you do not understand the first example. Also the c value can ONLY BE THE HYPOTENUSE VALUE. The hypotenuse is the longest side of the triangle. For example, 12 would be the C value on number one and in number two it would be 15.
2.) 14.5
3.) 10.3
4.) 18.8
5.) 8
6.) 15

>> 2x + 5 < x + 1 / 4 
>> 4 (2x + 5) < x + 1 
>> 4 × (2x + 5) < x + 1 
>> 8x + 20 < x + 1 
>> 8x - x < 1 - 20
>> 7x < 1 - 20
>> 7x < -19
>> x = -19 / 7
