Given parallelogram CASE, CE = x + 23, and AS = 2x + 10, find CE

andreyandreev [35.5K]

Answer:

CE = 36

Step-by-step explanation:

The opposite sides of a parallelogram are congruent , then

AS = CE , substitute values

2x + 10 = x + 23 ( subtract x from both sides )

x + 10 = 23 ( subtract 10 from both sides )

x = 13

Then

CE = x + 23 = 13 + 23 = 36

What is the length of side AC of the triangle?<br><br> Enter your answers in the boxes.

inessss [21]

Answer:

$AC=25$

Step-by-step explanation:

From the given figure, it can be seen that ${\angle}A={\angle}C$ , thus ΔABC is an isosceles triangle.

Therefore, $AB=BC$

⇒ $5x+5=7x-1$

Solving the above equation, we get

⇒ $5x-7x=-1-5$

⇒ $-2x=-6$

⇒ $x=3$

Now, substituting the value of x in AC, we have

⇒ $AC=6x+7$

⇒ $AC=6(3)+7$

⇒ $AC=18+7$

⇒ $AC=25$

Thus, the length of the side AC of the given triangle is 25 units.
