The angles measuring xx and 2x form a linear pair (straight angle) so the sum of their measures is 180°. Hence,
x+2x=180
3x=180
x=60
0

The parallel lines at the right are cut by a transversal. Find the value of x.
a. Angles 1 and 2 are corresponding angles, \(\displaystyle{m}∠{1}={45}°\), and \(\displaystyle{m}∠{2}={\left({x}+{25}\right)}°\).
b. Angles 3 and 4 are alternate interior angles, \(\displaystyle{m}∠{3}={2}{x}°\), and \(\displaystyle{m}∠{4}={80}°\).

Use what you just learned about negative slopes to solve this problem. A storm moves at a rate of 8 miles per hour. It is 200 miles away from Freeport and headed directly for this town. The equation y = 200 - 8x can be used to represent this function. Identify the slope and y-intercept and explain what they represent.
