<u>45x²</u> · <u>x² - 5x - 36</u> = <u>45x²(x² - 5x - 36)</u> = <u>45x⁴ - 225x³ - 1620x²</u> =
x - 9 x³ + 12x² (x - 9)(x³ + 12x²) x⁴ + 3x³ - 108x²
45 with a remainder of -360x³ + 3240x²
A line adds up to equal 180 degrees. And adjacent angles also add to equal 180 since they share a side on a line. So add them together and make them equal 180
9x - 7 + 8.5x + 4 = 180
17.5x - 3 = 180
17.5x = 183
x = 10.5
