A pendulum 45cm long swings through a vertical angle of 30 degrees.Find the height through which the pendulum bob rises.
Can you solve it using numerical trigonometry as I am currently learning about it.Thanks
Step 1: Solve for x, which is the length of the line between the ceiling and the point where the imaginary line from the pendulum bob meets the wall.
Step 2: Solve for h, which is equal to the length of the pendulum minus` ` x:
Therefore, the pendulum bob has risen 6cm.
