Answer: In Paralellogram ABCD adjacent angle are 180° i.e. /_A + /_B = 180° ___(1) Given :- /_ A 5 ____ =. __ /_ B. 4 i.e. 4/_A = 5/_B i.s. /_ A= 5/_B/4 Putting this in (1), we get 5/_B / 4 + /_B = 180° i.e. 5/_B + 4/_B = 720° i.e. 9/_B =720° i.e. /_ B = 720/9 i.e. /_B = 80° Therefore angle B is 80 degree Reply
Answer:
In Paralellogram ABCD adjacent angle are 180°
i.e. /_A + /_B = 180° ___(1)
Given :- /_ A 5
____ =. __
/_ B. 4
i.e. 4/_A = 5/_B
i.s. /_ A= 5/_B/4
Putting this in (1), we get
5/_B / 4 + /_B = 180°
i.e. 5/_B + 4/_B = 720°
i.e. 9/_B =720°
i.e. /_ B = 720/9
i.e. /_B = 80°
Therefore angle B is 80 degree
