Answer 1

Answer:

1 ]∠4+∠3=180° [linear pair]

   2x+3x = 180°

   5x = 180°

    x = 180/5

    x = 36°

    2x = 72°

    3x = 108°

    ∠4=∠2 [ vertically opp. angle ]

     ∠3=∠1 [ vertically opp. angle ]

   ∠4=∠6[alternate interior angle ]

   ∠3=∠5 [ alternate interior angle]

   ∠2=∠8[alternate exterior angle]

   ∠1= ∠7[alternate exterior angle]

   therefore,

   ∠1=108°

   ∠2=72°

   ∠3=108°

   ∠4=72°

   ∠5=108°

   ∠6=72°

   ∠7=108°

   ∠8=72°

2] ∠1 = ∠2[ alternate interior angle ]

   ∠2 = 123°

∠2+∠3=180° [ linear pair ]

∠3 = 180°-123°

∠3 = 57°

∠4+∠7=180°[linear pair]

∠7= 180°-∠4

∠7=180°-85°

∠7 = 95°

∠7=∠5 [ alternate exterior angle ]

∠5 = 95°
