Whether it is how far, how tall, or at what angle, knowing how to apply right angle trigonometry can help you to answer these questions. We start with a review of some basics about right triangles (0:45). If you know two sides of a triangle, then you can find the third side using the Pythagorean Theorem (1:10). If you know one side of a triangle and an angle in addition to the 90 degree angle, then you can find the remaining sides (2:10). What if you know two legs of a triangle - then you can use inverse trigonometric functions to find a missing angle (5:00).
The Question of the Day asks:(7:14)
Your mailbox is 10 m from your house, and the ledge of your bedroom window is located 5 m above the ground. How long would a piece of rope need to be to make a little zipline for your mail to travel to the box?
