Answer:
The value of m is 3
Step-by-step explanation:
We are given that ABCD is a parallelogram
Property of parallelogram : Opposite sides of parallelogram is equal
So, AB = CD and BC = AD
We are given that
BC =3m + 10
AD = 7m – 2
So, Using Property
BC=AD
3m+10=7m-2
12=4m
3=m
Hence The value of m is 3
