Question

10. If L A and B are two adjacent angles of a parallelogram if _A = 70'. then LB =
a) 70
b) 90
d) 180
c) 110​

Answer 1

Answer:

C) 110°

Step-by-step explanation:

sum of two adjacent angles of a parallelogram= 180°

<A= 70°

<A+<B=180°

70°+<B=180°

<B= 180°-70°

=110°

so <B = 110°

C) 110°
