Question

x + 22
10
a. x + 22 + 10 = 48
b. x + 22 - 10 = 48
c. x + 22 + x + 22 + 10 = 48
d. x + 22 + x + 22 + x + 22 = 10

Explanation:

Step1: Identify equal - length sides

The two slanted sides of the triangle are equal, each with length $x + 22$, and the base has length 10. Assume the perimeter of the triangle is 48.

Step2: Set up perimeter equation

The perimeter of a triangle is the sum of the lengths of its sides. So, $(x + 22)+(x + 22)+10=48$, which simplifies to $x + 22+x + 22 + 10 = 48$.

Answer:

C. $x + 22+x + 22 + 10 = 48$
