Hi,

One angle in a triangle has a measure that is three times as large as the smallest angle. 

The measure of the third angle is 45 degrees more than that of the smallest angle. 

smallest angle:  x

2nd angle:  3x

3rd angle: x + 45

Question states***

  x + 3x + (x+ 45) = 180°  

        5x = 135°  

         x = 27° , smallest angle.  largest is 81° 

and (3rd angle is 72°  )

 27°  + 81° + 72°   = 180°
