How many degrees do each of the complementary angles measure? (Hint: Let “x” represent one angle and “90 – x” represent the other angle. Then, write the equation and solve.)

to complete this square you have to rotate about the origin 270 degrees clockwise.

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
