tan-θ + sin 2 e-1 and sin θ cos θ, find the value ofn the Fig. I ,

1.	tan-θ + sin 2 e-1 and sin θ cos θ, find the value ofn the Fig. I , DE 11 BC . If AB = 6 cm, AD = 4 cm, EC-3 cm, find AC.Fig. 1
Answer» By converse of mid point if two sides are parallel then the ratio of the corresponding sides are equal so , ad/db = ae/ec ( ad = ab - ad) 4/2 = ae/3 cross multiplying ' ae = 6 cm so ac = ae + ec = 6+3 = 9 ac = 9 cm

Answer»

By converse of mid point if two sides are parallel then the ratio of the corresponding sides are equal

so ,

ad/db = ae/ec ( ad = ab - ad)

4/2 = ae/3

cross multiplying '

ae = 6 cm

so ac = ae + ec = 6+3 = 9

ac = 9 cm
