Final answer:
The length of side AB is 44 inches in an isosceles triangle ABC.
Step-by-step explanation:
In an isosceles triangle ABC, CA is represented as 4x + 10 inches and CB is represented as 6x - 28 inches. Since CA = CB in an isosceles triangle, we can set the expressions for CA and CB equal to each other:
4x + 10 = 6x - 28
Subtracting 4x from both sides and adding 28 to both sides, we get:
38 = 2x
Dividing both sides by 2, we find:
x = 19
Now, we can substitute the value of x back into the expression for AB to find its length:
AB = 3x - 13
Substituting x = 19:
AB = 3(19) - 13
AB = 57 - 13
AB = 44
Therefore, the length of side AB is 44 inches.
