Question

1. In the parallelogram ABCD, ZBAD + ZBCD = 140°, then the measure of ABC is​

Answer 1

Answer:

ABC=110°

Step-by-step explanation:

BAD+BCD=140° (given)

ABC=ADC=y (opp angles of ||gm are equal)

BAD+BCD+ABC+ADC=360° (angle sum prop)

140°+y+y=360°

2y=360°-140°

y=220°/2

y=110°

=>y=ABC=110°
