Answer:
The side of the terrace with the greatest length can be determined by analyzing the angles of triangle ABC.
Given that angle A is 55ᵒ, angle B is 65ᵒ, and angle C is 60ᵒ, we can use the properties of triangles to find the side with the greatest length.
In a triangle, the side opposite the largest angle is always the longest side.
Since angle B has the largest measure of 65ᵒ, side BC, which is opposite angle B, will have the greatest length.
Therefore, the correct answer is B. BC has the greatest length
