9x=27 is the perimeter 
perimeter is s1+s2+s3 
each length is 3x+9
        
             
        
        
        
1: True

I hope i helped :)</span>
        
                    
             
        
        
        
Answer:
x = 55
Step-by-step explanation:
a triangle's angles must equal when added up to 180. 
so 
76 + 49 + x = 180
combine terms 
125 + x = 180
x = 55

Math:9.75
Science:6
Step-by-step explanation:
Not 100% sure on those answers but here is hot to figure the problem out:
A point that falls outside the data set's inner fences is classified as a minor outlier, while one that falls outside the outer fences is classified as a major outlier. To find the inner fences for your data set, first, multiply the interquartile range by 1.5. Then, add the result to Q3 and subtract it from Q1.
