Question

(i need this answer fast any tell me ?)

Answer 1

here given,
angle B = 45°
angle C = 65°
Now
angle A + angle B + angle C = 180°[sum of all interior angle of triangle is 180°]
or, angle A + 45° + 65° = 180°
or, angle A + 110° = 180°
or, angle A = 180° -110°
therefore, angle A = 70°
then,
hence, side BC is the greatest side [ side opposite to the greatest angle is the greatest side]


hope this answer will help u:)
