These bisectors intersect each-other at 90 degrees. And it means that they are perpendicular. Since they are perpendicular, we find that there 4 congruent triangles and XY is parallel to WZ and WX is parallel to YZ. Additionally, opposite angles are equal. These two latter findings are the characteristics of the parallelogram.
Answer:
119.38
Step-by-step explanation:
the circumference is πd so it is 19 X 2, which is 38, times π, which is 38π. this equals 119.38

Step-by-step explanation:
it goes down consitantly by 2
Answer:
No solutions
Step-by-step explanation:
Let's solve your system by elimination.
10x − 9y = −10
20x − 18y = −28
Multiply the first equation by -2, and multiply the second equation by 1.
−2(10x − 9y = −10)
1(20x − 18y = −28)
Becomes:
−20x + 18y = 20
20x − 18y = −28
Add these equations to eliminate x:
0 = −8
