Find the scale factor for the dilation shown. A coordinate plane shows two diamond-shaped quadrilaterals (rotated squares), one smaller in black and one larger in red. The black figure has vertices P at (2, 0), L at (4, −2), R at (2, −4), and U at (0, −2). The red figure has corresponding vertices P′ at (4, 0), L′ at (8, −4), R′ at (4, −8), and U′ at (0, −4).

If A geometric diagram shows two large triangles. The upper triangle has vertices labeled A at the top left, B at the bottom left, and C at the top right. The lower triangle has vertices labeled F at the bottom left, D at the bottom right, and E at the top right. The slanted sides of the triangles run parallel to each other. The vertical sides on the left and right edges appear straight, with A above B on the left and E above D on the right.

Find the measure of each missing angle. [answer1] [answer2] [answer3] Two straight lines intersect at point O, forming four angles. One line runs from P in the upper left through O to R in the lower right. The other line runs from S in the lower left through O to Q in the upper right. The angle on the right side between the upward-slanting ray toward Q and the downward-slanting ray toward R is labeled 55°.

Find the value of each angle: Angle P = [answer1] Angle Q = [answer2] Angle R = [answer3] Angle S = [answer4] A four-sided figure is shown filled with a light blue shading. The bottom-left and bottom-right corners, labeled S and R, each have right angle markers. The left side is vertical from S to P, and the right side is vertical from R to Q. The top side slopes upward from left to right, with the angle at P labeled 5x minus 15 and the angle at Q labeled 3x minus 5. The bottom side is horizontal, connecting S to R.
