Answer 1

Answer:

2e = 100 + 42 (exterior angle property)

2e = 142

e = 71 degrees

now, e = 50 + f (exterior angle property)

71 = 50 + f

f = 21 degrees.

solved

Answer 2

Step-by-step explanation:

we know that,

42°+50°+50° + angle DAE = 180°. ( triangle sum property)

142°+ angle DAE = 180°

angle DAE = 180 - 142 = 38°

now,

38°+e+e = 180°. ( linear pair)

2e + 38° = 180°

2e = 180°-38= 142°

e = 142/2 = 71°

now,

50°+e+f+ angle DAE = 180°. ( triangle sum property)

50°+71°+38°+f = 180°

f = 180-159° = 21°

so e = 71° and f = 21°
