What is the sum of the interior angles of an octagon?  [answer1] 

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)°. A point labeled L lies on the slanted ray above and to the left of T.

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.

Find the area of the figure shown:  A trapezoid is shown filled with a light purple color. The top side, labeled 12 meters, and bottom side, labeled 18 meters, are marked with matching arrows. A dashed interior segment, labeled 21 meters, runs between the top and bottom sides forming a right angle with the 18 meter side.
