Question

A Quadrilateral ABCD circumscribes a circle, AB=6cm, BC=7cm,CD=4cm. Find length of AD

Answer 1

Answer:

AB+BC+CD=AD

Step-by-step explanation:

6+7+4=17cm

Answer 2

Answer:

3cm.

Step-by-step explanation:

As it circumscribes,

Construction: draw Ef and pq from both pair of sides of quadrilateral, now all ponts a b c and d are the external points of the tangents drawn to circle.

so AB+DC = As+Bc

so 6+4=AD+7

so AD=10-7=*3cm*
