# SAT Math Question (14) - Basic Trigonometry

I love basic trigonometry! It is so easy once you get the concept, so teaching it is no problem! Here is a guide to what you may see on the SATs. Enjoy my friends!

## Right Triangles with Labeled Sides

There are only so many they can give you... H - Hypotenuse (opposite the right angle), O - Opposite (opposite the given angle, theta), A - Adjacent (touching the given angle, theta).

## Some Examples

- A triangle has side lengths 5, 12, 13. What is one of the angles?

- Solve for x.

## Practical Example

A plane starts its descent with an angle of depression of 15 degrees. If it is 200 miles from the airport, how high is the plane?

splash-of-angs63 (49)7 years agoNice post! But I guess you sould have identified the perpendicular, base and hypotenuse as 'p', 'b' and 'h' respectively. I mean it will help readers to not get puzzled. Thank you :)
