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
If X is congruent to Z then they have to be the same number, then you add them and the result you substract it from 180 and that equals Y (remember that the sides of a triangle add up to 180)
Answer:
3x + x + 100° = 180°
⇔ 4x = 80°
⇔ x = 20°
Step-by-step explanation:
19-m since you are starting out with 18 and subtracting m from it
I believe that your answer would be A, 5-2i.
