Answer:
80° & 60°
Step-by-step explanation:
L y = 80° because L DAB & L ADC are alternate interior angles .
Now , L PBA = 100° - (80° + 40°) = 60°

Answer:
X = 60* and Y= 80*
Step-by-step explanation:
GIVEN
1.ABCD is a Trapezium
2.angle A = 100*
3.angle P = 40*
TO FIND
1. Angle Y
2. Angle X
PROOF
IN ABCD
angle A + angle Y = 180* (by co interior angles)
angle Y = 180 - 100 = 80* ( answer 1)
IN PDC ( triangle)
angle P + angle Y + angle X = 180* ( angle sum property of a triangle)
angle X = 180 - ( 80 + 40 )
Angle X = 60* ( answer 2)
