Answer 2

Answer:

185°

Step-by-step explanation:

As CA is parallel to FD,

ang. EFD = ang. BCA = x = 51° .... (1)

Now,

In ∆ABC,

ang. BCA + ang. CAB + ang. ABC = 180°

=> 51 + 83 + ang. ABC = 180°

=> 134 + ang. ABC = 180°

=> ang. ABC = 180 - 134

Thus, ang. ABC = 46° ...(2)

As CFBE is a straight line,

ang. CBA + ang. EBA = 180° ... (3)

Now, ang. EBA = y and ang. CBA = 46 ... From eq. (2)

therefore, substituting these values in (3), we get

46 + y = 180°

y = 180 - 46

y = 134° ....(4)

from (2) and (4),

x = 51°

y = 134°

therefore,

x + y = 51 + 134

x + y = 185°
