Answer 2

Answer:angle D = 22

angle AED = 68

Step-by-step explanation:

using alt interior angle rule

angle BEC = 42

therefore

angle BEC + angle DEC + angle AED = 180 (angles on a straight line)

42 + 70 + angle AED + 180

angle AED = 68

now in triangle AED

angle A + angle D + angle E = 180 (ASP)

68 + 90 + angle D = 180

angle D = 22
