Question

in the figure angle A = 60 degree angle B = 70 degree find B and C​

Answer 1

B=70°

C=180°-60°=120°[Because sum of the opposite angles of a quadrilateral is 180°]

D=180°-70°=110°

Answer 2

ABCD is a cyclic quadrilateral.

The sum of opposite angles is equal to 180° in cyclic quadrilateral.

So Angle A + Angle C = 180°

Angle B + Angle D = 180°

Angle A + Angle C = 180°

60 + Angle C = 180°

Angle C = 180 - 60 = 120°

Angle C = 120°

Angle B + Angle D = 180°

70 + Angle D = 180°

Angle D = 180 - 70 = 110

Angle D = 110°
