Hi Briana.
All triangles have a total internal measurement of 180 degrees from their angles. Isosceles triangles have two similar side lengths, and one different side length also known as the base. Considering we have the base, we can determine the side lengths by using the following equation:
2x + 24 = 96
Let's get to solving!
2x + 24 = 96; subtract 24 from both sides.
2x = 72; divide both sides by 2 to solve for the measurement of each side length.
x = 36;
Your answer is B.) 36
I hope this helps!
