Question

Three angles of quadrilatera
are 100° ,98°,92° then the fourth angle is ​

Answer 1

Answer:

70

Step-by-step explanation:

Answer 2

Answer:

ANGLE D = 70°

Step-by-step explanation:

SUM OF ALL ANGLES OF QUADRILATERAL IS 360°

GIVEN :

Angle A = 100°

Angle B = 98°

Angle C = 92°

Angle D = x

ACCORDING TO QUESTION:

Angle A + Angle B + Angle C + Angle D = 360°

100° + 98° + 92° + x = 360°

290° + x = 360°

x = 360° - 290°

x = 70°

HENCE MEASURE OF ANGLE D = 70°
