Answer:
Opposite angles are congruent
Step-by-step explanation:
The parallelogram has parallel opposite sides and also the opposite sides are congruent. Few other properties of parallelogram are -
- It has two pairs of parallel opposite sides.
- Its diagonals bisect each other.
- It has two pairs of equal opposite angles.
- It has two pairs of equal and parallel opposite sides.
So, the answer is D.) opposite angles are congruent.
Simple....
you have 7(5x+3)+3(12-x)....
just take them apart....
7(5x+3)
distribute the 7...
7*5x=35x
and
7*3=21
Now, the other part...
3(12-x)
Distribute the 3...
3*12=36
and
3*-x=-3x
Now, add what you have found....
35x+21+36-3x
32x+57
Thus, your answer, A.
C. 145°
Explanation:
angles A and D are opposite adjacent.
I think is D , hope i answer fast enough haha :D
