Question

in a triangle ABC d and e are the points on sides ab and ac respectively such that de is parallel to bc if ad=6 cm db=9 cm ae=8 cm find ac

Answer 1

Answer:

ac=7cm

Step-by-step explanation:

ad+db

6cm+9cm

15cm

ac+ae=ac

15cm=8cm+x

X=15-8

=7cm

Answer 2

To find = AC

Hence, Using Thales Theorem,

ADBD=AECE

44.5=8AC

AC=4.5×84 cm

AC = 9 cm
