Trigonometry and Angle Calculations

Front

What is Trigonometry?

Back

Trigonometry is a branch of mathematics that studies the relationships between the angles and sides of triangles, particularly right triangles.

Front

Define the angle of elevation.

Back

The angle of elevation is the angle formed by the horizontal line and the line of sight to an object above the horizontal level.

Front

What is the formula to find the height of an object using the angle of elevation?

Back

Height = Distance * tan(Angle of Elevation)

If a ladder leans against a wall, what relationship does it have with the ground and the wall?

Back

The ladder, the wall, and the ground form a right triangle where the ladder is the hypotenuse.
