Use a protractor, or draw a picture using known angles
Explanation:
- Draw a graph. The Y axis is at a 90 degree angle to the x axis
graph{ [-1, 10, -1, 5]} - half of a 90 degree angle is a 45 degree angle
graph{x [-1, 10, -1, 5]} - halfway between a 90 degree angle and a 45 degree angle is a 67.5 degree angle graph{2x [-1, 10, -1, 5]}
- 72 degrees should be slightly above (steeper than) this angle
You can also use a protractor for more accurate measurement.
And, Here is the accurate graph for
graph{y= (tan (2pi/5))x [-14.13, 17.9, -6.65, 9.37]}
Just graph the equation
