Step-by-step explanation:
since in a triangle each side must be shorter than the sum of the other 2 sides (otherwise the end points cannot connect, and there is no triangle), the necessary inequality condition must be
side < 1 + 2 = 3
so, 
side < 3
for a lower limit let's go through the cases
1 < 2 + side (is always true)
2 < 1 + side
 1 < side (side must be larger than 1)
and again
side < 1 + 2 = 3
 side < 3
so the full restriction for the third side is
1 < side < 3
 
        
             
        
        
        
Answer:
<h2>For the first triangle, <u>x equals 22cm.</u></h2>
Here's how:-
x is the altitude or height of the triangle. To find it, we can use the Pythagoras theorem:-

The base is 120cm and the hypotenuse is 122cm
Putting this in the equation, we get:-



 = 484
 = 484
altitude = 
<h3>altitude = 22cm</h3><h2><u>So, x = 22cm</u></h2>
 
        
             
        
        
        
Answer:
Most of the time you can go on a website that can cauculate it. 
Step-by-step explanation:
How to cauculate the MAD: 
Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set. Finally, round to the nearest tenth.
 
        
             
        
        
        
1. 6+ -35 = -29
2. -29+ 6 = -35
1. 37 + -33 = 4
2. -33 + 4 = 37
