Question

(e) in the given figure, a : b = 4:5 and angleXZR =
117. The value of (b + c) is
() 130
(i) 128°
(ii) 123°
(iv) 115°​

Answer 1

Answer:

This is your right answer

Answer 2

Answer:

Ans :- 120°

Hence,

from figure we can see that angle a and c are on a straight line .

so,

angle A+C = 117°

52° + C = 117°

C= 117° -52°

C= 65°

angle (b+c)

65°+65° =( 130 °)

Hence ( b+c ) = 130°
