An architect designs two similar triangular patios. The first patio has angle measures of (x − 15)°, (y + 5)°, and 75°. The second patio has angle
measures of (x + 20)°, 40°, and 65°. Find the values of x and y.

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
