Aria, Evelyn, and Arjun are architects designing a new city layout. They are working on a blueprint where road g is parallel to road k, and road t intersects roads g and k. Based on their blueprint, which statement about the mysterious angle x at the intersection is true?

• The value of x is 180, because the labeled angles in each blueprint are supplementary and the sum of the measures of supplementary angles is 180 degrees.

• The value of x is 90, because the labeled angles in each blueprint are complementary and the sum of the measures of complementary angles is 90 degrees.

• The value of x is 44, because the sum of the measures of the labeled angles in each blueprint is 180 degrees.

• The value of x is 136, because the labeled angles in each blueprint are congruent.

Imagine Aria, Zoe, and Mason are architects designing three buildings. The buildings are designed in such a way that when viewed from above, they form a right triangle. They are trying to figure out a puzzle related to the area of their buildings. Can you help them solve it? Which statement is true?

• The sum of the areas of Aria's Building (N) and Zoe's Building (L) is equal to the area of Mason's Building (K).

• The sum of the areas of Aria's Building (N) and Zoe's Building (L) is greater than the area of Mason's Building (K).

• The sum of the areas of Aria's Building (N) and Mason's Building (K) is equal to the area of Zoe's Building (L).

• The sum of the areas of Aria's Building (N) and Mason's Building (K) is less than the area of Zoe's Building (L).
