Answer:
Step-by-step explanation:
From the figure, it is given that ABCD is a parallelogram and since, opposite sides of the parallelogram are equal, thus
BC=AD
⇒6-x=x+2
⇒x=2
Thus, BC=AD=2 units.
Also, the opposite angles of the parallelogram are equal, therefore
∠BAD=∠BCD
⇒100-y=12+y
⇒y=44
Therefore, ∠BAD=100-44=56° and ∠BCD=12+44=56°
Thus, ∠BAD=∠BCD=56°
Pairs Tiles
1. 56 Value of m∠DAB
2.4 Length of BC
3. 44 Value of y
4. 2 Value of x
