Question

quadrilateral ABCD circumscribes a circle If AB=6cm, BC=7cm and CD=4cm find length of AD

pls explain with diagram​

Answer 1

Answer:

3cm

Step-by-step explanation:

We know that when a quadrilateral circumscribes a circle then sum of opposes sides is equal to the sum of other opposite sides.

AB + CD = AD + BC

6 + 4 = AD + 7

10 = AD + 7

AD = 10 - 7

AD = 3 cm
