Step-by-step explanation:
ABCD is a rhombus, so
AB = BC = CD = DA
AB || BC || CD || DA
In Δ ABD
AD = AB
angle ADB = angle ABD ( angle opposite to equal side are also equal)
angle ABD = 50°
angle ABD + angle ADB + angle DAB =180
50° + 50° + angle DAB = 180°
angle DAB = 180° - 100° = 80°
angle DAB = 80°
angle DAB = angle DCB (opposite angles)
angle DCB = 80°
angle DCB + angle CBA = 180° (co - interior angles)
angle CBA = 180 - 80 = 100°
angleCBA = 100°
angle CBA = angle ADC = 100°
So all angles of rhombus are :
angleABC = angleADC = 100°
angle DAB = angle DCB = 80°
