Triangle CDE is an isosceles triangle with CD = DE. If CD = 9x - 25, DE = 6x + 8, and CE = 10x - 73, find x and the measure of each side.

Final answer:

To find the value of x, equate CD and DE, simplify the equation, and solve for x. Substituting the value of x back into the given expressions for CD, DE, and CE, we find the measure of each side in Triangle CDE.

Step-by-step explanation:

To find the value of x, we can equate CD and DE since it is an isosceles triangle. So, we have the equation:

9x - 25 = 6x + 8

Simplifying the equation, we get:

3x = 33

Dividing both sides by 3, we find that x = 11.

To find the measure of each side, we substitute the value of x back into the given expressions for CD, DE, and CE:

CD = 9(11) - 25 = 94

DE = 6(11) + 8 = 74

CE = 10(11) - 73 = 37

Therefore, the measure of each side in Triangle CDE is CD = 94, DE = 74, and CE = 37.
