Ur answer is c to ur question
Answer:
y = 7/3 and x = 1
Step-by-step explanation:
Since this figure is a parallelogram, the opposite sides of the parallelogram are congruent, therefore:
2y-9 = y-2 and 3x+1 = 5x-1
y and x can now be found algebraically:
2y-9 = y-2 3x+1 = 5x-1
3y-9 = -2 -2x+1 = -1
3y = 7 -2x = -2
y = 7/3 x = 1
So y is 7/3 and x is 1. When showing your work I would also mark the opposite sides of the parallelogram as congruent to one another (see image as reference).

Step-by-step explanation:
13.01 < 13.1 because there is a 0 in the tenths place in 13.01 and there is a 1 in the tenths place in 13.1
Answer:
Step-by-step explanation:
Since ABC is an equilateral triangle, thus AB=BC=AC=x, therefore
The perimeter of ΔABC=36
⇒AB+BC+AC=36
⇒x+x+x=36
⇒3x=36
⇒x=12
Thus, AB=BC=AC=12.
Now, Since ΔADC is isosceles triangle, therefore AD=DC=y.
Perimeter of ΔADC=40
⇒AD+DC+CA=40
⇒x+y+y=40
⇒12+2y=40
⇒2y=28
⇒y=14
Therefore, AD=DC=14
Thus, Length of sides of ΔABC are AB=BC=AC=12 and Length of sides of ΔADC are AD=DC=14.
