How do you find the angle of a graph?
How do you find the angle of a graph? If you have a line of slope m=rise/run, and θ is the angle it makes with the x-axis, then tan(θ)=m. This is because if you draw a right triangle from the angle, the rise/run ratio is the same as the side opposite of the angle divided by the adjacent side. What is a central angle in a circle graph? A central angle is an angle with its vertex at the center of a circle, with its sides containing two radii of the circle. In the figure above, ∠PZQ,∠QZR , and ∠RZP...
