Question

choose the correct alternative​

Answer 1

Answer:

1.According to property of cyclic quadrilateral-:

angle A + angle C=180°

65° + angle C=180°

angle C=180°- 65°

angle C=115°(ans)

2.diagonal=16 cm

let the sides be 'a' cm

Accoding to Pythagoras theorem:-

a^2 + a^2 = 16^2

2(a^2)=256

a^2=256/2

a^2=128

a=√128

a=8√2

Therefore the side is 8√2 cm

3. AB=4cm,PQ=6cm,QR=9cm

Accoding to the question-:

AB=PR,BC=PQ,AC=QR

Therefore BC=6cm
