Question

ABCD angle A = 110 degree, angle B = 30 degree, angle C = half of angle a, then angle D = ?

Answer 1

Answer:

angle A = 110°

Therefore, angle C = 110°/2 = 55°

Some of angles of any quadrilateral = 360°

Angle ( A + B + C + D ) = 360°

110° + 30° + 55° + angle D = 360°

195° + angle D = 360°

Angle D = 360° - 195° = 165°
