Question

□LMNO is a parallelogram .if <L =100°then the measure of <m =?​

Answer 1

Answer:

<L + <M = 180°

<100°+ <M = 180°

<M= 180°- 100°

<M = 80°

Answer 2

Answer:

<m=80 degree.

Step-by-step explanation:

<LMNO is parallelogram (given)

<L=100° (given)

then, <o=100° (opposite angles of parallelogram are equal)

now, by linear pair we can say that

<m+<o = 180°

<m + 100° =180°

<m = 180°- 100°

<m=80°

hence proved.
