Find the value of x.   [answer1]  A horizontal line passes through point T, with point A on the left and point E on the right. From T, a ray extends upward and to the left through point L. Two adjacent angles are formed along the straight line at T: the angle between the left horizontal ray and the slanted ray is labeled (4x + 2)°, and the angle between the slanted ray and the right horizontal ray is labeled (8x − 2)°.

Write the translation in coordinate notation.   A coordinate plane shows two congruent rectangles, one in green and one in red. The green rectangle is below the x-axis with vertices A at (1, −2), B at (1, -1), C at (−2, -1), and D at (−2, −2). The red rectangle is above the x-axis with corresponding vertices A′ at (4, 1), B′ at (4, 2), C′ at (1, 2), and D′ at (1, 1). Both rectangles are aligned with the axes, having horizontal top and bottom sides and vertical left and right sides.
