Answer 1

Step-by-step explanation:

We know a quadrilateral circumscribes a circle then

the sum of lenght of opposite sides must same.

In this question,ABCD is a Quadrilateral.

Here,AB=6 cm

CD=5 cm

AD=7 cm

For this type of question,AB+CD=AD+BC

=>6+5=7+BC

=>BC=6+5-7=4

Answer 2

Answer:

Step-by-step explanation

AB+CD=BC+AD

so 3+5=4+AD

This implies that

8=4+AD

So AD= 4
