Answer:
A
Step-by-step explanation:
supplementary angles add up to 180
angle cgr and kga are vertical angles so they are equal
that makes the two angles in question add up to 180
 
        
             
        
        
        
Answer:
If M<6=72
Step-by-step explanation:
Then What is M
M=72/6 =12
so M<7=12 by 7=84
therefoe M<7=84
 
        
             
        
        
        
If the triangle is a right triangle, then 
       (3x)² + x² = (10)² .
         9x² + x² = 100
             10x²  = 100
                 x²  =  10
                 x  =  √10  =  approx. 3.1622...
If ' x ' is <em>anything less than √10</em> , then the short sides are too short
to make a right angle at the top, and the angle where they meet
is obtuse.
' x ' has to be greater than  2.5 ... otherwise the two short sides
can't stretch far enough to reach both ends of the long side (10) .
So, if    2.5  <  x  <  √10 , then there is a triangle, and it's obtuse.
