Tangent calculations

Front

What is the tangent ratio?

Back

The tangent ratio is defined as the ratio of the length of the opposite side to the length of the adjacent side in a right triangle. It is expressed as: tan(θ) = opposite/adjacent.

Front

If you know the lengths of the opposite and adjacent sides, how do you find the angle using tangent?

Back

To find the angle θ, use the formula: θ = arctan(opposite/adjacent). This will give you the angle in radians or degrees.

Front

What is the relationship between tangent and the sides of a right triangle?

Back

In a right triangle, the tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

Front

Which trigonometric function would you use to find the angle if you have the opposite and adjacent sides?

Back

You would use the tangent function.

Front

What does the term 'opposite side' refer to in a right triangle?

Back

The opposite side is the side opposite to the angle you are considering in a right triangle.

Front

What does the term 'adjacent side' refer to in a right triangle?

Back

The adjacent side is the side that is next to the angle you are considering, excluding the hypotenuse.

Front

How do you calculate the tangent of an angle in a right triangle?

Back

Tangent is calculated by dividing the length of the opposite side by the length of the adjacent side: tan(θ) = opposite/adjacent.

Front

What is the tangent of a 45-degree angle?

Back

The tangent of a 45-degree angle is 1, since the lengths of the opposite and adjacent sides are equal.

Front

In a right triangle, if the opposite side is 3 units and the adjacent side is 4 units, what is the tangent of the angle?

Back

The tangent of the angle is 3/4 or 0.75.

Front

What is the purpose of using tangent in real-life applications?

Back

Tangent is used in various applications such as engineering, architecture, and physics to calculate angles and distances.
