1. BC ( length opposite to largest angle is longest )
2. 90°
angle B + angle C = 180 ( sum of adjacent side of a parallelogram is 180° )
angle B = x
angle C = y
2x + 2y = 180
x + y = 90
in triangle BOC
x + y + BOC = 180
90 + BOC = 180
BOC = 90°
hope it helps...

Are you sure that the side opposite to the laregest angle is longest?
hey
How 90 comes .Please explain .
Thanks a lot. Where from you?

104. side BC is the longest because the side opposite to the largest angle is the longest angle
105. 100' is the answer
105. 100' is the answer
Are you sure about the rule? How 100 comes? I think it will be 90
no
it will be obtuse angle so it is 100
hey my first answer is wrong
ok
