It is the first answer. Notice that if you multiply it out you get 6x + 30, and they have factored out the 6.
Answer:
Step-by-step explanation:
Both angles are supplementary (they add up to 180°)
This means that (10x) + (6x - 12°) = 180°
(10x) + (6x - 12°) = 180°
10x + 6x - 12° = 180°
16x - 12° = 180°
16x = 192°
x = 12°

The diagonal's length is about 3.5 inches; to solve, use the Pythagorean theorem (a^2 + b^2 = c^) to determine the length of the diagonal using one of the two triangles it forms by cutting the square in half. One triangle has three sides: 6 in, 6 in, and the unknown diagonal.
6^2 + 6^2 = c^2 Plug in the known sides
36 + 36 = c^2 Simplify
72 = c^2 Simplify
~3.5 = c Take the square root of both sides
