Question

Can someone pls tell me what is dis questions answer

Answer 1

in triangle ade and bce
we have
ad=bc
de=ce
angle ade =angle bce [90°+60°=150°]
hence triangle ade is congruent to triangle bce so,
angle dae=angle cbe (by cpct)




angle dab =angle cba = 90°
angle dae +angle eab =angle cbe angle eba
we have proved above that
angle dae=angle cbe

so,
angle eab = angle eba
therefore
ea = be [ opposite side of equal angle ]
