Angle 1 and angle 2 form a linear pair. if m angle =5x+9 and m angle 2=3x+11,find the measures of both angels.

∠1 = 109°    ∠2 = 71°

Step-by-step explanation:

If the two angles form a linear pair, then their sum is 180°

  ∠1      +     ∠2     = 180°

(5x + 9) + (3x + 11) = 180

              8x + 20  = 180

              8x          = 160

                x          = 20

∠1 = 5x + 9

    = 5(20) + 9

    = 100   + 9

    = 109

∠2 = 3x + 11

     = 3(20) + 11

     =    60  + 11

     =         71

  CHECK:

∠1   + ∠2 = 180°

109° + 71° = 180°

     180°   = 180°  

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
