triangles are always 180 degrees, seems like you have the outer corner, which is 116

180-116 is 64

Also it seems like you have a symmetrical triangle, which means x is (180-64)/2

Both  angles across the equal sides are themselves equal  = x

 

And using the exterior angle theorem,,,we have that

 

116  =  x  + x

 

116   = 2x       divide both sides by 2

 

58° =  x

 

 

cool cool cool
