Front

What is 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.

Front

How do you find the length of a shadow using trigonometry?

Back

Use the formula: Shadow Length = Height / tan(angle of elevation).

Front

What is the tangent function in relation to a right triangle?

Back

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

Front

What is the sine function in relation to a right triangle?

Back

In a right triangle, the sine of an angle is the ratio of the opposite side to the hypotenuse.

Front

What is the cosine function in relation to a right triangle?

Back

In a right triangle, the cosine of an angle is the ratio of the adjacent side to the hypotenuse.

Front
