Devin and Sierra were playing a learning game in which they had to virtually sort points, lines, and planes from a collection of points that appeared on an electronic game board. For a correct response, the board flashed green. If an incorrect response was given, or if a duplicate of a previous response was offered, the board would buzz and flash red. Pretend you are playing the game and using the points below. Name 3 points, 3 lines, and 3 planes. Note: The points do not all necessarily lie in the same plane.

Suppose M is between L and N. LM = (1/2y + 3), MN = (4y + 7/2), LN = 135. Find the value of y.

Two angles are complements. 30 less than twice the larger angle equals twice the smaller angle. Find the measures of the two angles.
