Question

answer this question please

Answer 1

angle ABC=BCD(ALTERNATE INTERIOR ANGLES)

BCD=40 SO ANGLE C IS 40

ANGLE BAD=ANGLEADC(SAME REASON)

SI ANGLE D IS 50

ANGLR O+ANGLEC+ANGLE D =180
(SUM OF TRIANGLE ANGLE IS 180)

SO ANGLE O IS 90

BY VERTICAL OPPOSITE ANGLE ANGLE O s OPPOSITE WILL BE EQUAL 90

Answer 2

Given: -
AB||CD
Angle A = 50°
angle B = 40°
then,
by angle sum property...
angle A +angle B + Angle AOB = 180°
50°+ 40° + angle AOB = 180°
angle AOB = 180°-90°
angle AOB = 110°
and,
angle AOB = angle COD (vertically opposite angles)
angle COD= 110°
Angle A = angle D
angle D = 50°
angle B= angle C
angle C = 40°
Hence,
the required angle are: -
angle C = 40°
angle D = 50°
angle COD = 110°
angle AOB = 110°
hope this will help uh...
